Description: # Bit Slicer 9k
        * Super fast bitslicing. 
        * bitshift speed without bitwise complexity.
        
        #### Install
        ```python3
        pip install bitslicer9k
        ```
        
        #### Help(Slicer9k)
        ```
        Help on class Slicer9k in module bitslicer9k:
        
        class Slicer9k(builtins.object)
         |  Slicer9k(bites)
         |  
         |  Methods defined here:
         |  
         |  __init__(self, bites)
         |      From bytes to bits
         |  
         |  as90k(self, num_bits)
         |      return bitslice as 90k time
         |  
         |  asdecodedhex(self, num_bits)
         |      return decoded hex of a bitslice
         |  
         |  asflag(self, num_bits=1)
         |      returns one bit as True or False
         |  
         |  ashex(self, num_bits)
         |      return the hex value of a bitslice
         |  
         |  asint(self, num_bits)
         |      Starting at self.idx of self.bits, slice off num_bits of bits.
         |

        ```
        
        
         I used to do this
        ```python3
           from struct import unpack
             
            sync,two_bytes,one_byte = unpack('>BHB', packet[:4])
            tei = two_bytes >> 15 
            pusi = two_bytes >> 14 & 0x1
            ts_priority = two_bytes >>13 & 0x1
            pid = two_bytes & 0x1fff
            scramble = one_byte >>6
            afc = (one_byte & 48) >> 4
            count = one_byte & 15
        ```
         Now I use bitslicer9k and do this
        ```python3
            from bitslicer9k import Slicer9k
            
            header= Slicer9k(packet[:4])
            sync=header.asint(8)
            tei=header.asflag(1)
            pusi=header.asflag(1)
            ts_priority=header.asflag(1)
            pid=header.asint(13)
            scramble=header.asint(2)
            afc=header.asint(2)
            count=header.asint(4)
        ```
        
        #### Example Usage
          *  Parse  a SCTE 35 splice information section from a hex encoded string
        
        ```python3
        
        >>> from bitslicer9k import Slicer9k   
            
        
        >>> bites= bytes.fromhex( 'FC302F000000000000FFFFF00506FEAEF17C4C0019021743554549480000077F9F0808000000002CA56C97110000C4876A2E')
        
        
        >>> class Splice_Info_Section:    
                def __init__(self,bs):
                    self.table_id =bs.ashex(8)
                    self.section_syntax_indicator = bs.asflag(1)
                    self.private = bs.asflag(1)
                    self.reserved=bs.asint(2)
                    self.section_length = bs.asint(12)
                    self.protocol_version = bs.asint(8)
                    self.encrypted_packet =  bs.asflag(1)
                    self.encryption_algorithm =bs.asint(6)
                    self.pts_adjustment = bs.as90k(33)
                    self.cw_index = bs.ashex(8)
                    self.tier = bs.ashex(12)
                    self.splice_command_length = bs.asint(12)
                    self.splice_command_type = bs.asint(8)
              
        
        >>> bs=Slicer9k(bites)
        
        >>> sps=Splice_Info_Section(bs)
        
        >>> vars(sps)
        
        {'table_id': '0xfc', 'section_syntax_indicator': False, 'private': False, 'reserved': 3, 'section_length': 47,
        'protocol_version': 0, 'encrypted_packet': False, 'encryption_algorithm': 0, 'pts_adjustment': '0.000000', 
        'cw_index': '0xff', 'tier': '0xfff', 'splice_command_length': 5, 'splice_command_type': 6, 'descriptor_loop_length': 25}
