Disallow spacing between function identifiers and their invocations (func-call-spacing)

[feross]

https://eslint.org/docs/rules/func-call-spacing

When calling a function, developers may insert optional whitespace between the function’s name and the parentheses that invoke it.

Option: "never" (default) disallows space between the function name and the opening parenthesis.

Examples of incorrect code for this rule with the default "never" option:

/*eslint func-call-spacing: ["error", "never"]*/

fn ();

fn
();

Examples of correct code for this rule with the default "never" option:

/*eslint func-call-spacing: ["error", "never"]*/

fn();
