Update authors and nonce type in snip-9

[tarrencev]

Added Cartridge as an author and updated nonce type in OutsideExecution.

This is an optimization we already have implemented in the Controller. It enables nonce channels for outside execution which supports using a bitmask as nonce value, allowing reuse of a single storage slot for 128 txns rather than requiring a new storage slot for every transaction.

For reference, the nonce check in Cairo:

let (channel, mask) = outside_execution.nonce;
let current_mask = self.outside_nonces.read(channel);
let (and, _, or) = bitwise(current_mask, mask);
assert(mask != 0 && and == 0, 'ctrl/invalid-outside-nonce');
self.outside_nonces.write(channel, or);

why not incremental nonces instead?, then you we can have 2**252 txs in the same channel

another thing, i think this is better than the tupple, actually i think tuples are not allowed in snip12

    { name: "Nonce Channel", type: "felt" },
    { name: "Nonce Value", type: "felt" },

i will really like to add another change if we are pushing revision 3, Nonces by caller: so the same nonce could be valid for different outside_execute.caller. it helps prevent many DoS issues

maybe we should rename the title of this PR to "Snip-9 Revision 3"
