ignore any exception if errors='ignore'

[Kebniss]

as explained in #99 errors='ignore' was not universal.

I wanted to add a test but I don't know how to test exceptions

Thanks @Kebniss , looks good 👍 left one small comment. Regarding testing, passing an empty string as html will trigger an error in the parser (document is empty), so I think we could use it for a test.

Looks good, thanks @Kebniss ! Left a comment regarding more granular exception handling in unification.

Looks good 👍 left a few minor comments

codecov fails because some exceptions are not tested, however I cannot come up with an input that is extracted ok but then fails when uniforming data

[lopuhin]

@Kebniss looks good! I think it's expected that we can't test all exception code paths. Left one small comment, apart from that it's ready to merge 👍

Looks great, thanks @Kebniss 👍
