Mock paymaster

[tuler]

Proper packaging and versioning of mock paymaster, copied from https://github.com/pimlicolabs/mock-aa-environment/tree/main/mock-verifying-paymaster

The idea is to publish the package as @cartesi/mock-paymaster, with a npm bin, and then installing it inside the SDK in another PR.

How can I test.

I executed docker compose up but don't know what to expect.

If this compose will be part of the cartesi run, we could remove it from this package when we have it working integrated with the cli.

[tuler]

The docker compose is a test one that runs the two services that the mock-paymaster connects to, the anvil and alto.

You can test by running the compose and then executing the pnpm run start with two env variables defined, the ANVIL_RPC and ALTO_RPC.

I tried to not make any change at all to the original source code. It's only a packaging and versioning addition to the original work.

I'm getting this:

ANVIL_RPC=http://localhost:8545 ALTO_RPC=http://0.0.0.0:4337 pnpm run start
