Foldseeks mishandles Content-Length header

[Lukas.Bauer@…]

The following bug report has been submitted:
Platform:        macOS-14.6.1-arm64-arm-64bit
ChimeraX Version: 1.10.dev202501142332 (2025-01-14 23:32:44 UTC)
Description
If foldseek query response via https returns a Content-Length header than ChimeraX code fails to read the results because it uses the length as if it were an integer but it is in fact a string.

[Tom Goddard]

Fixed.

Added conversion of string to integer when reporting the size of the foldseek results used in download progress status messages. For some reason my Foldseek responses never have a Content-Length header so I am puzzled why you get them. Maybe you use a proxy server that adds the Content-Length.

[Tom Goddard]

Oops. Forgot to check in this fix. Checked it in now so it will be in the January 17, 2025 daily builds.
