addComponent with initial value about bitecs

thanks for the detailed explanation and pretty much what I anticipated.

i try to make bitECS as performant as possible, and let the users degrade the performance where appropriate for their particular use-case. one of the keys to this is creating as little garbage as possible so that the GC has nothing to clean up, and that is accomplished by pre-allocating everything up-front. technically this new function of yours, while syntactically cleaner, creates an object every time you add a component. the original addComponent creates no objects and therefor has no chance creating any garbage to clean up.

my goal with bitECS is to do less for the user and remain as flexible and performant as possible for all potential use-cases. this function does more for the user, and creates objects, so i won't be adding anything like this into the API.

not to say i discourage functions like this, just want to keep GC-generating things outside of the API. all depends on your use-case :)
