Blocked by: #5022

Allow cast to be use to create subscriptions using eth_subscribe.

Subscribe to newHeads:

cast subscribe block
cast subscribe block --full
cast subscribe block --number

Ideally, events should be automatically decoded using local abi or etherscan source.

cast subscribe event  --address 0x00000 'eventSignature()`
cast subscribe event --topics '[0x00000, 0x000001]'
cast subscribe event --address 0x000000

Could add an alternative that does not decode events:

cast subscribe logs  --address 0x000000

Subscribe to newPendingTransactions:

cast subscribe tx --pending 
cast subscribe tx --pending  --from 0x0000
cast subscribe tx --pending  --value 1
cast subscribe tx --pending  'transfer(address,address,uint)`

Subscribe to tx using newHeads

cast subscribe tx  
cast subscribe tx --from 0x0000
cast subscribe tx  --to 0x000 --selector 0x000000
cast subscribe tx 'transfer(address,address,uint)` --from 0x00000
