Merge #15573: dead code: Remove dead option in HexStr conversion

56f1d28d9b dead code: Remove dead option in HexStr conversion (Lenny Maiorani)

Pull request description:

  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.

  Solution:
  - Remove unused `fspaces` option.
  - Remove associated unit tests.
