Improvements in address code

[yabirgb]

What was wrong?

Parts of the code had redundant code

How was it fixed?

simplified the code while keeping the same checks. For the to_checksum_address function I tried to see if it was possible to improve its performance but I didn't manage to get anything meaninful

➜  eth-utils git:(main) ✗ hyperfine --warmup 3 --runs 10 'uv run --no-project reg.py'
Benchmark 1: uv run --no-project reg.py
  Time (mean ± σ):     234.1 ms ±   1.2 ms    [User: 214.9 ms, System: 17.9 ms]
  Range (min … max):   232.8 ms … 236.4 ms    10 runs

➜  eth-utils git:(main) ✗ git checkout improvements
Switched to branch 'improvements'
➜  eth-utils git:(improvements) ✗ hyperfine --warmup 3 --runs 10 'uv run --no-project reg.py'
Benchmark 1: uv run --no-project reg.py
  Time (mean ± σ):     232.0 ms ±   0.9 ms    [User: 213.0 ms, System: 17.9 ms]
  Range (min … max):   230.8 ms … 233.6 ms    10 runs

This is reading and checksumming 10k addresses

Todo:

• Clean up commit history
• Add or update documentation related to these changes
• Add entry to the release notes

here it removes a redundant function call

[yabirgb]

the cast is not needed here. Only when the argument has type Any
