The rkisp1 IPA has some utility functions to convert between fixed
and floating point numbers. Move those to libipa so they're available
for use in other IPA modules too.

There was an issue where using map to store the test cases meant that
the test for ignoring unused bits was skipped because of clashing keys.
Fix this by moving the offending test out of the loop.
While at it, also change the arbitrary floating comparison precision to
be more precise.
Also fix a missing documentation brief.
