.jpeg images raise 'NotAnImage' exception due to possible typo on base.rb

[Cathodeo]

Issue:

A valid .jpeg image triggers the 'NotAnImage' exception, despite
.jpeg being on the list of supported extensions

Possible cause:

base.rb has the following extensions:

def extensions
@extensions ||= {
'image/png': '.png',
'image/jpeg': '.jpg',
'image/jpg': '.jpg',
'image/gif': '.gif',
'image/bmp': '.bmp',
'image/tiff': '.tif'
}
end

Which seems to expect .jpeg files to be named .jpg instead.
If ' 'image/jpeg': '.jpg' is replaced with 'image/jpeg': '.jpeg'
and the library is recompiled, the issue seems to be solved.

Might be an environment specific issue, but I could reproduce the issue with any .jpeg file prior to the edition of base.rb
