chore: configure nimalyzer

[vil02]

In this PR I propose to use nimalyzer as a static analysis tool for this repository. I add a workflow nimalyzer.yml and a config file .nimalyzer.cfg. Please notice that some of the rules are temporarily commented out (with having them in, the check would simply fail). I suggest to create a issue, where we can discuss which rules to activate and trace the progresses of fixing the warnings.

The config file is a simplified version of the official example. All of the nim-files are the object of the analysis.

Please notice that nimalyzer.yml will run one per week. Due to the fact that the tool is still under development, I think it would be a good idea to know early enough if something breaks or changes.

Related to #16.

I am sorry for my very late reaction.

It seems too early for me to integrate nimalyzer.
I think it would be better to wait a little bit before incorporating it.
I'll check locally the output of nimalyzer.

EDIT: I ran nimalyzer on the repository:
Below is the output of nimalyzer after changing some options to adapt the configuration file for v.0.9:

1f7a2d0 is similar to #78.

Regarding the early stage of nimalyzer: are there some alternative tools? I would use it as long as it would not enforce some strange workarounds. We could also pin the version by installing it with a command like

nimble install nimalyzer@0.9 -y

The output of nimanalyzer is strange:
"[11:37:32] ERROR rule: params, procedure constructHighway* line: 27 parameter 'randomFrequency' doesn't use int or string as type."
I don't understand the "doesn't use int or string as type.". I understand from it that the nimanalyzer tool doesn't support finding unused parameters if there are not of these types.

I don't know any alternatives for this kind of tool.

Re-read the documentation of Nim analyzer, there is a bug with the rule:
"check params used all".

Doc: https://www.laeran.pl.eu.org/repositories/nimalyzer/wiki?name=paramsUsed%20rule
Since both checkType and declarationType may use the keyword "all", there might be a parser error here, that replaces "used" by "all" for the checkType (when the "all" is actually a declarationType thing). I'll open an issue in the Fossil repository if I manage that.
