lithium triethylborodeuteride not recognized #230

Closed IngvarLa closed 1 year ago

IngvarLa commented 1 year ago

Think this is the normal way to name 

[Li+].CC[B-](CC)(CC)[2H]

Opsin is happy with lithium triethylborohydride.
Compare with Lithium aluminiumtetradeuteride and Lithium aluminium tetradeuteride which are both recognised.

This was surprisingly inelegant to support as OPSIN doesn't allow implicit deuterium atoms. e.g. lithium triethylborohydride has one deuterium, but lithium borohydride has four!

I also added support for the less common tritium analogue (borotritide)
