Feeds Parser Setting accept custom character for default delimiter.

First let me say FEEDS is awesome.

I saw issue https://www.drupal.org/project/feeds/issues/946342 → about the available default delimiters are hard coded, at least they were 15 years ago :).

My not urgent feature request is to be able to specify a custom delimter for Feeds Parser Setting. I have found on the fringes some people are using ALT-30 and ALT-31 as delimiters. I had run into this for multivalue fields that had commas breaking Feeds Tamper Explode and found I could use ALT-31 in my Views data export instead of a comma for multivalue fileds and have Feeds Tamper Explode handle multivalue fields that had commas in them. So yes, that was awesome. My ass-umption was none of my fields would have ALT-31, it is rare.

So I thought, heck I will use ALT-30 instead of commas for my CSV file generation... whoops FEEDS CVS parser only has a choice of five characters for default delimter unlike Feeds Tamer Explode.

We can get by without this feature request, but I wanted to put it up as a request/suggestion for Feeds Parser Setting.
