regression: no more line_color_filter

[jeremybmerrill]

it comes up every now and again that tabula-extractor allowed users (in the Ruby version only -- I don't think there were hooks into the CLI version) to only use lines whose RGB matches a certain lambda for Spreadsheet/Lattice mode.

This doesn't exist in tabula-java

Filtering lines by color is currently implemented in tabula-extractor as a Proc that's passed to the ObjectExtractor. That is, filtering is done at page mining time.

Maybe we could mine every Ruling instead, and provide some kind of option to the Extractors that let the user pass a lambda (that accepts a Ruling as its argument) to allow for more generic filtering.

What do you think?

Yes, great. 💯
