weakref / transient

[simonseyock]

the class PackedCoordinateSequence uses a transient SoftReference. This might be tricky to convert correctly with WeakRef in typescript. It would be possible to provide an alternative implementation. That being said, the jsts implementation is missing this file altogether. @bjornharrtell do you know why that is the case? Is the PackedCoordinateSequence and PackedCoordinateSequenceFactory not needed in jsts?

Also I am a little confused why this line does not cause an error because the file does not exist:
https://github.com/bjornharrtell/jsts/blob/e18f6e86c4ba9f7cda3cbce39b0e590625982c43/src/org/locationtech/jts/geom/impl/PackedCoordinateSequenceFactory.js#L6

I think PackedCoordinateSequence is an opt in alternative memory model for coordinates that I never considered. It has like you suspect probably never been in working order and I think it is rarely used also upstream.
