fix: variable casing

[AuHau]

nph would not compile under Nim 2.0.14 because casing of the variable names does not match declaration.

nph compiles fine with 2.0.14 but what you've likely done is adding the --stylecheck:error flag when trying to compile (it is not on by default in nim).

For this higher level of case correctness to be maintained, this PR should add the stylecheck flag to nph's own CI as well, probably via config.nims, or there will be regressions.

Oh pardon my ignorance then 😅

Will do, thanks for the pointer!

@arnetheduck done.
