bladeRF-cli: Removed binle/binbe options. Binary data is host endianness

These changes are based upon those provided by engidea for Issue #64,
with some additional little naming changes.

To avoid having to deal with compiler-specific endianness macros,
the fixup routines contain the converion macros even for the
little-endian host case, assuming these will be optimized out, given
that they are generally empty macros.
