Support tree shaking (google-libphonenumber is huge)

[C0Nd3Mnd]

Using class-transformer-validator results in google-libphonenumber being included in the webpack bundle (even though tree shaking is enabled and no phone number validators are being used).

This was fixed in class-validator itself, see:

• Smaller bundle size typestack/class-validator#258
• fix: google-libphonenumber is huge typestack/class-validator#248

I'm wondering if there is an "easy" fix for this package?

Install newer version? class-validator is just a peer dep

I use version 0.12.2. I think the problem is that class-transformer-validator is importing the whole class-validator package. When I leave class-transformer-validator out of my project, the bundle doesn't include google-libphonenumber and is significantly smaller.

It's importing only a few functions 😕

class-transformer-validator/src/index.ts

Lines 1 to 7 in 5d25d52

	import {
	validate,
	validateSync,
	validateOrReject,
	ValidatorOptions,
	} from "class-validator";
	import { plainToClass, ClassTransformOptions } from "class-transformer";

Hm I see. I'm gonna have to dig deeper then. I'll post here if and when I find a possible solution.
