refactor: adhere mostly to StandardJS guidelines (#1657)

This commit changes the whole codebase to adhere to all StandardJS
guidelines rules except semicolons, since the removal of semicolons
affect pretty much all lines, and the final diff is very hard to follow
(and to assess other more involved changes).

In a nutshell:

- When using `function`, we now require a space before the opening
  parenthesis
- If a line with operators is broken into multiple lines, the operator
  should now go after the line break
- Unnecessary padding lines are now forbidden

There were also some minor things that the `standard` CLI caught that I
updated here.
