Duplicate family- to be block anr report to xrelease source

We do not apply the misspelling/normalisation rules of the names index to uninomials. Genus names are often very much alike and a single character does make a difference.

But my feeling is that this is a bit too strict and we could come up with some common misspellings like double characters that should be applied? For binomen we do this, seems to me we could apply the same also for monomials:

    // normalize frequent variations of i
    s = i.matcher(s).replaceAll("i");
    // remove repeated letters→leters in binomials
    s = removeRepeatedLetter.matcher(s).replaceAll("$1");
    // normalize frequent variations of t/r sometimes followed by an 'h'
    return trh.matcher(s).replaceAll("$1");

See #892 for a generic suggestion to improve the de-duplication of monomials

Decision for the family Ismariidae has been apply, I like very much the proposal about monomials
