Code formatting standards

[GraxCode]

CFR does have some small flaws at code formatting.

Examples that i found:

new line before imports / extends
space between ... in method parameters ("Object ... objects" instead of "Object... objects")
no new line after label definition (block0: for (...))

A fair point, but styles are subjective - I mention in https://github.com/leibnitz27/cfr/blob/master/contributing.md - I'm not massively bothered about coding styles where there's any disagreement in the wild, given that (if you're particular about that sort of thing) it's trivial to run eg google-format-java over output (with your own personal preferences set).

Re labels - due to the nature of the beast, CFR is occasionally going to generate a lot more labels than you'd find in production code - I find condensing like that a readability bonus.

I've had a wander trying to actually find a single style guide that explicitly mention varargs ellipsis. Google java doesn't actually seem to care.

https://rules.sonarsource.com/java/RSPEC-3878 is the only one I found, and this has the extra explicit space!

I have to confess, I prefer it, for no particular reason, (though perhaps that's my c++ talking).

I'm going to close this - it's a minor subjective stylistic issue which can easily be patched up with a formatting tool. While this may seem a little aribtrary given #167 , that is more of an intrustive change, which is harder for a trivial style checker to apply.
