binaryUrl configuration has hard coded URL path

[miurahr]

When using download site that each file has its own unique URL, and set binaryUrl configuration to set binary,
it become 404 error with https://example.com/foo/boo/.sha256

It is hard coded and there are no way to specify sha256 url.

You can find up-to-date sphinx standalone binary at
https://codeberg.org/miurahr/sphinx-standalone/releases

and binary URL for linux is https://codeberg.org/attachments/d7d1f85d-2c49-41c4-828d-cc6432f67b27 and sha256 is https://codeberg.org/attachments/21a306fe-4205-4d51-ba4b-54d9bc38523d

Is there any way to solve a situation?
