Use rbs-inline and rewrite bitmap.rb

[Little-Rubyist]

I'll be installing rbs-inline, which we discussed previously.
rbs-inline requires writing the type information to .rb files and generating .rbs files with rbs-inline --output.

I were also considering installing rubocop-on-rbs, but decided to pass on it because rubocop has not use yet.

Just in case, I want to confirm the development process.
Will we generate rbs file by rbs-inline --output on local and commit generated files so that released gem will include rbs files same as before?

@yui-knk
Yes, that's correct.
If we forget to generate, we should be able to notice because the steep check will fail.
