documents provider: mime type map fails with .JPG

[chrysn]

The mime type for .JPG files exported to the Storage Access Framework via the documents provider is the fallback application/octet-stream; thus, image viewers won't open it.

Given that file extensions are usually case insensitive and the library appears to only recognize lower-case variants (tried .html, .doc and .txt), and that digital cameras often store uppercase letters, I suggest that lowercasing the extension before here as a mitigation.

(I can't tell whether there might be better ways than using webkit's mimetypemap (maybe libmagic?) -- but lowercasing would mitigate the immediate issue).

Thank you for maintaining termux and the documents provider; it makes dealing with the android file system limitations much better!

Thanks! This has been fixed in version 0.61 of the app, which has now been released and should be available in Google Play within a few hours (and on F-Droid within a day or so)!
