add linting options

[bircni]

I enabled some lints in clippy to improve the style of the code.
There are some todos open with missing panic docs.
It is not that good to use unwraps as we don't want to crash the users experience, maybe instead use the crate anyhow to safely handle errors.

Thanks for such thorough work.

About using unwraps - totally agree. But I think we will come to this after the Layout feature is delivered and we start to stabilize APIs approaching to stable release. I will consider anyhow for sure.

What do you think about enhancing linter in the .github/workflows linter step?

[bircni]

now also enhanced the workflow

[bircni]

still working on another suggestion - maybe I can finish that later on!

[bircni]

@blitzarx1 I started adding anyhow - maybe you could have a look at it?

[blitzarx1]

lets extract anyhow changes to separate PR.

Also I am not sure this is the right time to add anyhow usage, while I am mid adding Layout feature. Let us return to anyhow after the Layout when we will be on stabilization track.

@bircni I am ready to continue wiht this PR, but without anyhow changes.

[bircni]

was just a check gonna revert them and finish the pr to make it ready for review finally!

[blitzarx1]

Good begining for the stabilization track
