refmt and compiler warnings

[dvisztempacct]

I wanted to quiet down compiler warnings of bs-ajv.

Somehow a bunch of redundant externals were declared, which was the majority of the warnings.

I removed one unused function (it didn't seem to match the documented interface of the foreign function anyhow) and exposed one (also unused) function in the Ajv module signature.

The rest are unused variables in pattern match destructurings and such...
