pradosoft#904 TBitHelper Utility class for dealing with bits and endian

- Bit Mirroring
- endian flipping
- color bit shift
- unsigned right bit shift
- has LongLong
- # bits needed (given a number, how many bits is needed to represent it)
- checking System Endian
- negative zero float checking
   - check for floats as negative including -0.
   - check for -0 specifically.
- converting float to half float and mini float (Fp16, Bf16, Fp8-e5m2, and Fp8-e4m3 are supported directly).  General utility function for taking a float and outputting an arbitrary exponent and mantissa.
