`print-unimath.opm`: Missing `\mith` #131

In the "catalogue" printed by print-unimath.opm in section for codes U+10001 to U+1EEF1 where lowercase latin letters are typeset in math-italic (\mita...\mitz), the \mith, e.g. the lowercase italic "h" is missing.

Symbols used in another place are not repeated in the Unicode-math block of characters. The U+0210E (Planck constant) is equal to \mith, so Unicode standard doesn't declare "italic h" again and the code U+1D455 is reserved (unoccupied). See https://en.wikipedia.org/wiki/Mathematical_operators_and_symbols_in_Unicode and https://github.com/mvoidex/UnicodeMath/issues/22.
