new features

navigate into textfiles using hotkeys (v, k)
close various UI elements by repeatedly hitting the Escape key
doubleclick files/folders to open them (in the grid view, when multiselect is enabled)
--s-wr-slp sets a delay between socket writes, simulates a slow network during downloads
--s-wr-sz sets socket write size, default 256 KiB (was hardcoded 32 KiB until now)
- this increase download speed by ~50% (to around 3 GiB/s) when running on windows / where sendfile is unavailable

bugfixes

when uploading two files with the same name and size, only the first file got uploaded
- so now it's also possible to upload the same files you just searched for without the refresh jank
- discovered thanks to rockylinux serving the same package in multiple pools, nice
when full-preload is enabled, also do regular preloading so the decoder has a chance to prepare (fixes gapless playback)
- and kill the preloaders if they don't finish in time so free up network
additional preloading fixes for ogv.js, only affecting apple devices when playing ogg/vorbis/opus audio:
- disable full-preload since ogv skips the browser cache somehow
- swap between the ogv instances to preserve cached audio
- still a bit of silence left between tracks as the decoder boots up but that is the price you have to pay for using proprietary garbage
ctrl-a now only selects the text within the focused codeblock in text documents
minor correctness fix regarding chunked uploads
avoid crc32 collisions in filenames
- affected the media player and file selection, but was unlikely to happen

prefer fpool on linux as well, since btrfs and zfs (and probably others) perform better with it
