species epithets with a "dot" should not parse

[dimus]

We have the following examples (after => is how normalized version should look.)

Graphis scripta L. a.b pulverulenta => Graphis scripta L.
Cetraria iberica a.crespo & barreno => Cetraria iberica
Lecanora achariana a.l.sm. => Lecanora achariana
Arthrosporum populorum a.massal. => Arthrosporum populorum
Eletica laeviceps ab.lateapicalis Pic => Eletica laeviceps

[alexander-myltsev]

infraspecies depends on word. word2sep allows dots. Need to discuss how to handle this.
