feat(cast/selectors): add optional selectors resolving

[cdump]

Motivation

4byte selector lookups for cast selectors was requested in comments #6684 (comment)

Solution

Add optional selectors resolving (--resolve, default=false).
After the #6719 has been merged, we don't have a problem with a lot of openchain API calls.

$ cast selectors --resolve $(cast code 0xdAC17F958D2ee523a2206206994597C13D831ec7)

0x06fdde03                              name()
0x0753c30c      address                 deprecate(address)
0x095ea7b3      address,uint256         approve(address,uint256)
0x0e136b19                              deprecated()
0x0ecb93c0      address                 addBlackList(address)
0x23b872dd      address,address,uint256 transferFrom(address,address,uint256)
...

output with | tr ' ' '.' | tr '\t' '|' (spaces replaced with . and tabs replaced with |)

0x06fdde03|.......................|name()
0x0753c30c|address................|deprecate(address)
0x095ea7b3|address,uint256........|approve(address,uint256)
0x0e136b19|.......................|deprecated()
0x23b872dd|address,address,uint256|transferFrom(address,address,uint256)
...

output is readable by humans (columns are aligned) and by shell scripts (no and \t chars in column values)
