/**
* Merges two objects and removes null values if "shouldRemoveNullObjectValues" is set to true
*
* We generally want to remove null values from objects written to disk and cache, because it decreases the amount of data stored in memory and on disk.
* On native, when merging an existing value with new changes, SQLite will use JSON_PATCH, which removes top-level nullish values.
* To be consistent with the behaviour for merge, we'll also want to remove null values for "set" operations.

Is "fastMerge" actually a good description? Is it actually faster...? Would something like mergeWithoutNullValues make more sense? Or customMerge...?

@flodnv We already have fastMerge in lib/utils.js. I just declare this function in d.ts file to support ts
