Make sharp.limitInputPixels configurable & more stable

[moinmoin]

I have searched the existing feature requests, both open and closed, to make sure this is not a duplicate request.

• Yes

The feature

Problem description: Huge orthodata TIFs are scattered in an external library. These bring down the immich instance frequently when thumbnails are generated.

Thumbnails are generated on miniature (250p) and preview level (720p).

Version affected: 2.6.2
Server has 14GB Mem assigned

Suggestion:

• Make sharp.limitInputPixels configurable via ENV setting

Setting:
IMMICH_PROCESS_INVALID_IMAGES = true

Currently the following error leads to a restart of the server:
