Fixed issue with NFC reading LUD-17 cards

[Talej]

Description

There was an issue reading Bolt Cards / LUD-17 LNURL NFC where the first 2 characters from the URL were stripped.

This change should allow this format to work while still maintaining previously supported formats.

Note: My NFC cards that I had on hand only supported a maximum of 140 bytes so I wasn't able to test with a bech32 encoded LNURL

Love seeing the initiative here. Code looks clean enough.

Are you using a Boltcard from CoinCorner?

Are you using a Boltcard from CoinCorner?

I have tested it with 2 cards - one connected up to CoinCorner and the other through the LNBits Boltcard plugin.

Both using LUD-17 so no bech32 encoding
