Feature: Handling fees

[Liongrass]

We could create a lnbits user account for @laiseebot

Everytime the bot creates a Laisee, it first sends the appropriate fee to the @laiseebot, as if the laiseebot was another user. This can happen silently in the background.

I am not sure I will have time to address the fee issue.

there are some new extensions that do split payments, i am not sure how stable they are but there isn't anything for custom fees for groups of users. e.g. members have discounted fees vs public. Perhaps a new extension will need to be written for LNBits.

At the moment, putting 100 SAT into the account and creating a Laisee over 100 SAT will result in an error. We should encourage at least a 1% "buffer" for fees in the account, as defined by LNBits

Added 1 sat default fee for now, it appears to work on lnpay.co back end, please test on your intsance. @Liongrass

Refactor Laiseebot to use split payments extension, should be stable enough now, as of 20 Apr 2023. (I hope). Also see article https://bitkarrot.substack.com/p/lightning-prisms-with-lnbits
