feat(utils): partitionByKey && mergeActiveKeys

[josepot]

Hopefully this will allow us to deprecate the following utils:

• split
• collect
• collectValues

While also providing a simpler way to create subscriptions for parametric bind Observables.

@voliva could you please finish this?

Code coverage went down to 99.53%...

I know that we've had this conversation "offline" before, but I really think that the order of the return value of partitionByKey should be reversed: first the inner-observable-getter and then the observable of keys... :thinking:

Combinekeys test has a typo: emmit vs emit

Fixed! Thanks!
