print-unimath.opm: Missing \mith

[dousamichal0807]

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).
