Warn if bad filter

[nsheff]

Giving a bogus filter fails silently:

eido convert https://raw.githubusercontent.com/databio/bedshift_analysis/master/pep_main/project_config.yaml -f bogus_filter

It should instead say bogus filter not found. options are: {filters}. Or something.

I think you're running an outdated version, it raises an error in my hands:

[mstolarczyk@MichalsMBP eido](dev): eido convert https://raw.githubusercontent.com/pepkit/nf-core-pep/master/config.yaml -f test
Traceback (most recent call last):
