Rewrote bin_to_hexadecimal to use Python's built-in int(s, 2) and hex() instead of a manual lookup table and bit-grouping loop. The old approach had a padding bug: inputs whose length was already a multiple of 4 got an extra 4 zeros prepended, so '1010' came out as '0x0a' instead of '0xa'. The new approach skips padding entirely and lets the stdlib handle it correctly. Also added a guard for "-" as input, which previously slipped past the empty-string check and raised an unhelpful ValueError about non-binary values. Removes BITS_TO_HEX, the divmod padding expression, and the grouping loop. Doctests updated to reflect the corrected output.
