Remake to have /core and @types

[m10rten]

Types take up a lot of space in the package.
To improve this, types need to moved to the @types/validatees package to be created seperately.

creation of a validatees/core package/folder is to split te core feature from the less relevant feature.

users should be able to choose either the validatees/core or the full validatees version.
@types/validatees should include all, and there will be no @types/validatees/core because it will be not worth it.

[m10rten]

@types will be done on Future release since this will require a pull request to the @DefinitelyTyped org.

[m10rten]

/core will require to make an internal package where /core has own package.json and registry.

[m10rten]

Same can be done for the CLI in /cli

[m10rten]

Where the prefix for both packages could be @validatees

[m10rten]

This has been picked up: @jetvil/types replaces ` validatees/types
@jetvil/core sums up core functionality, easy to use.
CLI will be added later on.

custom @types will not be done, since we include types as standard.
