Use standard formatter

[martinsumner]

Apply a standard formatter to the code e.g. erlfmt

https://github.com/martinsumner/leveled/tree/mas-i318-erlfmt - it is a big change

@martinsumner I was looking for some bigger project doing this :)
Thinking of using erlfmt too for VerneMQ. Seems you didn't have any issues so far?

[martinsumner]

It just worked straight away, although I have one line which is now not showing as covered by rebar3 cover, and I can't work out why.

It is such a big change in terms of git blame though, given that this project doesn't have a lot of external participation I'm not sure it is worth merging in the PR. I'm going to think about it for a few days, perhaps I just need to get used to the opinionated formatting - at the moment I'm not finding it easier to read.

I accidentally stumbled upon this issue while looking at leveled. One thing that helps with big diffs is new option introduced in git 2.23 --ignore-rev and --ignore-revs-file that allows blame to skip over some specific commit - it works great locally, but its integration with various tools (like github) is rather patchy at the moment. It's used by some big projects, nonetheless, like clang.

@michalmuskala thanks, I didn't even know this option.
