feat: Allow felt252 short strings on init_calldata

[rsodre]

Is your feature request related to a problem? Please describe.

Currently, we can pass only numbers and addresses to dojo_init() through a profile config init_calldata.

Would be good to allow felt252 short strings.

EVEN BETTER: make it generic enough and accept anything, like sozo --calldata

Describe the solution you'd like

Use sozo execute prefixes to format init_calldata

$ sozo execute --help
  -c, --calldata <CALLDATA>
          The calldata to be passed to the system. Comma separated values e.g., 0x12345,128,u256:9999999999. Sozo supports some prefixes that you can use to automatically parse some types. The supported prefixes are:
                            - u256: A 256-bit unsigned integer.
                            - sstr: A cairo short string.
                            - str: A cairo string (ByteArray).
                            - int: A signed integer.
                            - no prefix: A cairo felt or any type that fit into one felt.

Describe alternatives you've considered

None

Additional context

A good usage example for short strings (and why I need it) is to pass base_uri to an ERC-721 token contract.

# sepolia profile
init_calldata = [
  "sstr:https://testnet.pistols.gg", # base_uri
]

# mainnet profile
init_calldata = [
  "sstr:https://play.pistols.gg", # base_uri
]

Hello, would love to work on this!

@edisontim still interested to tackled that?

[glihm]

@edisontim if yes, the idea is to move the calldata_decoder that is inside bin/sozo into dojo/world and re-use it a bit everywhere it can apply. 👍

Hey @glihm, I'm still up for it yeah!
