Add the scanned unknown word to ignored word list in the config file

Is your feature request related to a problem? Please describe.
Let's assume you are planning to setup the spell checker first time for a project. Most of the time, your project would contain lot of unknown words(not found in dictionary), but are project specific. When you scan, you will get lot of errors with those unknown words. But you don't want them to be renamed as they are project specific. So, you manually add them to cspell.json file to be ignored. This I feel a very tedious process. It happened to me today.

Describe the solution you'd like
For the very first scan, we can add the list of unknown words to the config file automatically and let the user to make decision about it. Since 90% of them needs to be ignored and only 10% is to be corrected for spelling.

Additional context
I am not sure any other solution exists already, but I think it would be a cooler one if have it.

You make an excellent suggestion. On boarding a new project is currently more painful than it needs to be.

Related to #3, #2301

@Jason3S This instruction is what I wanted. Will use it.

Here is my feedback seen from a beginner eye. We can include the above instruction explicitly in the npm page(https://www.npmjs.com/package/cspell) or atleast a link to it. Helpful for onboarding.

Or as suggested in #3, we can have some init command to automate this process.

Thanks.
