Disable max-len rule for import and export statements

[chmanie]

Because it's just annoying. Here's the rule:

"max-len": ["error", {
    "ignorePattern": "^import [^,]+ from |^export | implements",
    "ignoreComments": true
}],

We probably also want to allow using long strings when using backticks

e.g.

"ignorePattern": "^import [^,]+ from |^export | implements | `.{30,}`",
