Don't copy archives to temp files in local source

[FooIbar]

Closes #134

[AntsyLich]

Does it not make loading slower due to SAF?

[FooIbar]

I mean, we are already using SAF.
It's not like we can bypass it unless requesting MANAGE_EXTERNAL_STORAGE.

Benchmark for a ~340 MB archive to load on test device

Before: 4000~5000 ms (~80% of time on copy to temp file)
After: 1000~1500 ms

[AntsyLich]

That's quite a bit of improvement. Seems okay to merge I guess. For the records can you also do a benchmark for some smaller sizes like ~20mb ~50mb ~100mb

Archive size [MB]	Avg. before [ms]	Copy time	Avg. after [ms]	Diff
3.27	1245	13%	1282	+2.9%
46.8	1387	20%	1435	+3.5%
103	1991	29%	1789	-10%
194	3514	74%	1238	-65%
339	6829	85%	1408	-79%

Everything looks fine tho how is the performance on lower ram devices 🤔

[FooIbar]

Will do more tomorrow.

The results above were obtained from a 2GB RAM AVD using debug build.
It may not represent real user experience, so I did another one on a 12GB RAM physical device with release build.

Archive size [MB]	Avg. before [ms]	Copy time	Avg. after [ms]	Diff
46.8	110	26%	96	-13%
103	150	36%	96	-36%
194	199	60%	95	-52%
339	280	72%	80	-71%

So apparently this doesn't work on Fold 5 and S24 Ultra

Could you provide more details to illustrate it?
