Lenny Maiorani 56f1d28d9b dead code: Remove dead option in HexStr conversion
Problem:
- Nothing uses the `fspaces` argument to `HexStr()` besides unit
  tests. This argument results in extra complexity and a small
  performance decrease within the function for branch evalulation.

Solution:
- Remove unused `fspaces` option.
