Feat/gas param

[kalote]

What kind of change does this PR introduce (bug fix, feature, docs update, ...)?

New gas configuration in the optional params setting:

const config = {
  ipfsGateway: 'https://YOUR-IPFS-GATEWAY/ipfs/',
  gas: 20_000_000, // optional, default is 2_000_000
};

const erc725 = new ERC725(schemas, address, RPC_URL, config);

I also removed the gasPrice from the constants.ts file as it was unused.

What is the current behaviour (you can also link to an open issue here)?

Fix #328

What is the new behaviour (if this is a feature change)?

I don't know anything about ts, so I've no idea what and how it works :D... but I would also recommend supporting setting the gas to 0 as a wildcard (or null or something) that would remove the call limit completely and let the node run with whatever cap it has itself.

Other information:

Also agree. 2_000_000 is so arbitrary. May be would exceed the gas block limit for some chains or would be irrelevant for others. Specially if there is no need to set it for a eth_call

[kalote]

So shall we set the default to 0? @CallumGrindle / @skimaharvey / @Hugoo ?

[kalote]

Default is 2_000_000 but can be change to 0 if needed via the param. I guess it can be added to the next release @CallumGrindle

[kalote]

Default gas value set to 1_000_000 (1Gwei).
