Matt Morehouse bd7ec84497 zpay32: help fuzzer generate valid encodings

It is very difficult for the fuzzer to create a valid checksum for each
serialized invoice, and we were therefore unable to fuzz deeper than
invoice decoding. We can help the fuzzer generate valid serialized
invoices by calculating and appending the checksum ourselves.

We also switch to using mainnet invoices to make it easier to find valid
invoices for seeding the fuzzer. We prepend the required "lnbc" prefix
ourselves to further help the fuzzer generate valid invoices.

zpay32

The zpay32 package implements a basic scheme for the encoding of payment requests between two lnd nodes within the Lightning Network. The zpay32 encoding scheme uses the zbase32 scheme along with a checksum to encode a serialized payment request.

The payment request serialized by the package consist of: the destination's public key, the payment hash to use for the payment, and the value of payment to send.
