Change to be independent of the args package

Issue

• close [Improve]: Remove packages from dependencies in yumemi_lints #138

Note

This PR will be the last package to be deleted in this issue,
so the issue will be automatically closed once the changes are merged.

Overview (Required)

args was used to parse command line arguments.
To eliminate the dependency, I manually rewrote it to the yumemi_lints specifications, referring to the internal structure of args.

Important

With this change, only the update option is accepted.
Specifying any other option will result in an exception.
There was some discussion about the help command, but it was deemed not important for yumemi_lints, so it has not been included in this PR.
Also, if there are no options, processing will proceed as usual.
These are guaranteed by the unit test system.

Confirm

• I verified that all tests were successful.
• All static analyses were confirmed to be successful.
• I manually verified everything that was being done by the unit tests.

Ready for review 🚀

I tried to implement it with extensibility in mind,
but even if more commands are added in the future, it will only be a few commands,
and I wanted to keep the implementation simple, so I removed all the extension classes.
Existing functions are guaranteed.
