Enable `--compile` for `generate fromTemplate` command

[This](https://github.com/asyncapi/cli/blob/master/src/commands/generate/fromTemplate.ts#L89) needs to be extended with new flag called: `--compile`

Would be good to also bump to use latest generator: `2.7.1`

It's going to work only with `AsyncAPINewGenerator` that has it enabled.

By default `compile` option in the library is set to `true` and would be great to allow people to pass `--compile=false`. This should speed up generation for templates like `@asyncapi/html-template` that are released with transpiled files and compilation is not needed.
