fix(kitty): dont error on non-existent temporary file after print

[hasezoey]

Due to kitty terminals deleting the file after fully reading it in known temporary directories.

This results in kitty to fail "local"(file) protocol with error from viuer "file not found" and falling-back to the "remote" way.

Originally part of #79

Thank you for catching this! While trying it out I noticed that local printing has a race condition. Sometimes the temp file will be deleted before Kitty attempts to read it. Adding a 10ms delay confirmed that.

I'm wondering whether we can avoid that by first transferring the image and then wait for a response when we display it, described here https://sw.kovidgoyal.net/kitty/graphics-protocol/#display-images-on-screen. I'll give it a shot

FYI, this is the "race condition" i mentioned in #79 (comment) and #90 (comment)

Already done in #90

Just to note, #90 is practically ready to be merged, after this PR (#87) and #85 plus a rebase, so it should be able to be updated & merged quickly right after those are done.

Closing as the code is part of #90
