Decaffeinate to ES6

[jankapunkt]

At first we need to decaffeinate the project before we can start improvements.

• Not many people understand coffeescript
• ES6 is stable and widely supported
• there should be no errors during conversion from coffee to es6
• we can skip the whole gulp processing
• we can use mocha+puppeteer for tests to ensure we don't break anything
• we can use prettier for linting and formatting

Tests are running again, however this is not release ready, there are the following things to be done (in sequence; prioritized):

• all tests currently run in node env but we need to run all other tests also using puppeteer to simulate minimongo usage within browser
• I commented out one line that requires navigator which we need to integrate with puppeteer
• tests should be restructured, they are currently hard to read and use often this. to attach things to the mocha environment but since we can easily use modules we should restructure tests
• test coverage is currently not very high and we might introduce regressions
• CI should be added using GitHub actions, fortunately I have already existing setups that will work so this is just one PR away
• rest of the code should be converted to es6 as well as decaffeinate did not convert to es6 100% this should also take the autogenerated comments from decaffeinate into consideration
• dependencies need to be updated and vulnerabilities need to be resolved
• meteor react native integration tests need to be added

@TheRealNate can you give me permission to open issues so we can keep track of things left todo?

@jankapunkt enabled issues. I'm also finishing up NPM setup shortly.

The recent push started the GitHub actions and they passed successfully, therefore this would also fix #3 and #2

@TheRealNate once this is merged the npm publish workflow should also pass, since npm ci is now working

@jankapunkt Thats awesome! Once you merge to master and create a new release the action should automatically publish the package to @meteorrn/minimongo.
