Flashbot bundle support

[0xsha]

hi guys,

I think this is extremely nice to have because like IPC it allows Vim to be used to beyond web As more and more builders support Flashbots-specific RPCs, it would be super cool if there were native Vim support. For starters, it can support just the main calls (base proivder) and then move towards full support with new endpoints and calls (which are not implemented by all RPCs).

Base provider (implemented by most providers):

eth_sendBundle
eth_cancelBundle
eth_sendPrivateTransaction
eth_sendPrivateRawTransaction
eth_cancelPrivateTransaction
eth_callBundle

Extended version (implemented by fewer RPC providers):

mev_sendBundle
mev_simBundle
etc

API : https://docs.flashbots.net/flashbots-auction/advanced/rpc-endpoint
Reference Code : https://github.com/flashbots/ethers-provider-flashbots-bundle/blob/master/src/index.ts

Thanks @jxom and team for the awesome client ❤️
