* WIP: Update for testing with Merge fixturenet. * Switch channel to take a *Transaction rather than []byte. This allows us to access the TX fields (eg, for logging) throughout its lifecycle. * Tweak message * Add code to check for TXs being put into blocks. * 0 == unlimited * Use -1, not 0, for unlimited. * golang 1.19 * Read contract from file.
