Message V0 sets the first bit of the message to 1.
This bit is not coincidentally the MSB in MessageHeader NumRequiredSignatures, which was redefined to be 7 bits instead of 8.
Basically, if NumRequiredSignatures & 0x80 == 1, then it's a message v0.
v0 adds MessageAddressTableLookup, a way to indirectly load a large number of accounts through the address table program.
(note: this is low priority imo, just posting this here so it's tracked)

Currently only legacy messages are supported.
