🧪 new features

up2k: improve file-hashing speed on recent versions of google chrome e3e51fb
- speed increased from 319 to 513 MiB/s by default (but older chrome versions did 748...)
- read the commit message for the full story, but basically chrome has gotten gradually slower over the past couple versions (starting from v133) and this makes it slightly less bad again
- hashing speed can be further improved from 0.5 to 1.1 GiB/s by enabling the [wasm] option in the [⚙️] settings tab
  - this option can be made default-enabled with --nosubtle 137 but beware that this increases the chances of running into browser-bugs (foreshadowing...)
up2k: fix errorhandler for browser-bugs (oom and such) 49c7124
- because chrome-bug 383568268 is about to make a surprise return?!
#168 fix uploading into shares if path-based proxying is used 9cb93ae
#165 unconditionally heed --rp-loc 84f5f41
- the config-option for path-based proxying was ignored if the reverse-proxy was untrusted; this was confusing and not strictly necessary

#166 the nixos module was improved once more (thx @msfjarvis!) 48470f6 60fb120
added usage instructions to minimal-up2k.js, the up2k-ui simplifier 1d308ee
docker: improve feedback if config is bad or missing 28b63e5

this release was tested using an unreliable rdp connection through two ssh-jumphosts to a qemu win10 vm back home from the bergen-oslo night train wifi

download link	is it good?	description
copyparty-sfx.py	✅ the best 👍	runs anywhere! only needs python
a docker image	it's ok	good if you prefer docker 🐋
copyparty.exe	⚠️ acceptable	for win8 or later; built-in thumbnailer
u2c.exe	⚠️ acceptable	CLI uploader as a win7+ exe (video)
copyparty.pyz	⚠️ acceptable	similar to the regular sfx, mostly worse
copyparty32.exe	⛔️ dangerous	for win7 -- never expose to the internet!
cpp-winpe64.exe	⛔️ dangerous	runs on 64bit WinPE, otherwise useless
bootable usb	┐(ﾟ∀ﾟ)┌	a surprisingly useful joke (x86_64)
