Apologies for taking some time to update this. I just made some changes to the list:

- Removed BTC-Cashier from the list since the source code hasn't been updated since 2018.
- Removed both Globee and Savvy as they're both not working anymore.
- Took off the "lightning support" column and replaced it with the lightning symbol. This should make it easier to spot.
- I also replaced the "requirements" column with "integrations" which now includes the supported plugins/integrations of the processor.

And I will be adding the processors suggested and some new ones soon. I just need to get some more info first.
