Introduce new expanded configuration

[Bullfrog1234]

This pull request makes the following changes:

• Expanded configuration functionality
• Validation of the configuration file (using yup) with some parts falling back to defaults if required
• Updated logging using chalk for formatting, including alerts on anytime it is falling back to defaults

The full config is now:

Field	Default Value	Type	Description
helpers	["authUserEmail", "authUserEmailIsVerified", "authUserUid", "existingData", "hasAmtOfWriteFields", "incomingData", "isAuthenticated"]	array(strings) | boolean	used to add helper functions to the output, this can be true to include all helper functions or false to include non of the helper functions or an array of the function names
custom_helpers_folder	null	null | string	path to user defined helper functions
rules_version	"1"	"1" | "2" | 1 | 2	which version is the rules written in
rules_folder	"rules"	string	folder where the rule fragments can be found
rules_output	"firestore.rules"	string	name of the file to output to
use_firebase_config	false	boolean	use the firebase config file firebase.json to get the rules output file name and location

This is the first time I have contributed to a library so please tell me if there is something I sould have done.

Hey @Bullfrog1234

Wow - thanks a lot for this PR - appreciate it! Seems to add a lot of new functionality!
I'm busy until the weekend, but will hopefully find time then to look at it and merge if all looks good.

You'll hear from me,

Thanks again
Pascal

Hey @lupas

No problem, hope it is all up to your standard

I found this library and started using it to build rules in 4 of my projects, I made the changes for those projects, but in the end I decided to share back with you to hopeful provide benefits to others

Cheers,
Bullfrog

Hey @Bullfrog1234

Finally had time to look at the PR and gotta say - this is some awesome work!
Thanks a lot for your effort - you really made this module shine ;-)

I tested it and fixed a small thing, but in general this looks great to me.

Already published it as v1.0.0.

Thanks again a lot - appreciate it.

Best regards & Merry Christmas!
