Previously, some costly things were causing the loading of GGUF files
and their metadata and tensor information to be VERY slow:

  * Too many allocations when decoding strings
  * Hitting disk for each read of each key and value, resulting in a
    not-okay amount of syscalls/disk I/O.

The show API is now down to 33ms from 800ms+ for llama3 on a macbook pro
m3.

This commit also prevents collecting large arrays of values when
decoding GGUFs (if desired). When such keys are encountered, their
values are null, and are encoded as such in JSON.

Also, this fixes a broken test that was not encoding valid GGUF.

While models are loading, the VRAM metrics are dynamic, so try
to load on a GPU that doesn't have a model actively loading, or wait
to avoid races that lead to OOMs

This library will give us the most reliable free VRAM reporting on windows
to enable concurrent model scheduling.

Our default behavior today is to try to fit into a single GPU if possible.
Some users would prefer the old behavior of always spreading across
multiple GPUs even if the model can fit into one.  This exposes that
tunable behavior.

Still not complete, needs some refinement to our prediction to understand the
discrete GPUs available space so we can see how many layers fit in each one
since we can't split one layer across multiple GPUs we can't treat free space
as one logical block

multiple templates may appear in a model if a model is created from
another model that 1) has an autodetected template and 2) defines a
custom template

* API app/browser access

* Add tauri (resolves #2291, #4791, #3799, #4388)

* Remove false time fields

* Struct Separation for List and Process

* Remove Marshaler

* put flash attention behind flag for now

* add test

* remove print

* up timeout for sheduler tests

The spelling of the term "request" has been corrected, which was previously mistakenly written as "requeset" in the error log message.

particularly useful for zipfiles and f16s
