CAIP-19: add supports for assets on Solana

[bumblefudge]

Very interested! Could I ask you to check out namespaces/template and caip104 and open a PR to fit the model of:
namespaces/solana/caip19.md
?
Ping me if you have any questions!

ChainAgnostic/namespaces#25 @bumblefudge something like this? Or do I need to open a PR in /CAIPs repo?

[romeo4934]

Yes token or mint could be fine!

[bumblefudge]

well-done, this is perfect!

[romeo4934]

I think it should be the mint address only to specify the asset for fungible token

I would pick spl-token as it is the way Solana called tokens:

so
Solana USDC token example
solana:4sGjMW1sUnHzSxGspuhpqLDx6wiyjNtZ/spl-token:EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v

@antoineherzog agree that we could consider using "spl-token" as the namespace here. Just tht spl-token-mint might be more explicit.

But mint address can be used to identify the asset type for both fungible token and non-fungible token. Could you elaborate on why "only to specify fungible token" ?

@antoineherzog @bumblefudge actually spl-token is better since it's also shorter. let's go with

solana:4sGjMW1sUnHzSxGspuhpqLDx6wiyjNtZ/spl-token:EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v

@antoineherzog how about just token because in CAIP-19 draft:

The method specific identifier is simply a [CAIP-19 Asset ID](https://github.com/ChainAgnostic/CAIPs/blob/master/CAIPs/caip-19.md) where all / characters are replaced by _, in order to comply with the DID spec.

solana:4sGjMW1sUnHzSxGspuhpqLDx6wiyjNtZ_spl-token:EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v

using both '_' and '-' makes it kinda confusing

ChainAgnostic/namespaces#25 is merged. So this is resolved.
