this PR adds Spanish language synonyms for street suffixes.

rebased to fix failing tests

Lets be sure to test this before we merge it. One character synonyms can probably have large and surprising impacts on both performance and result quality.

I have a different (and quite larger) list for this

Not sure what cost such a large list has and if it is worth it though

Definitely looks like a good thing to add overall.

I made a small note about the via,v synonym. I think single character synonyms can have surprising impact. Are we almost at the point where we want region specific synonyms? As far as I know, that synonym would not be super useful outside Spanish speaking countries, right?
