Handle absence of shared strings file

[dglsparsons]

Fixes #18

[AndyThurgood]

So this is def a fix. I wonder if we should raise an issue around the shared string implementation where we could refactor some of higher level code to handle such a potential absence. error.Is() feels like a yucky logic gate

[dglsparsons]

It's a bit of a weird logic gate, true. Not so different to just throwing a FileNotFoundEXception and letting the caller deal with it though.

Realistically the code only really has one function (outside of some helpers in this file) that's called - getSharedStrings - which is responsible for loading the sharedstrings file and populating the contents into a consumable format. So as long as that handles it correctly, is it such an issue? :)

[AndyThurgood]

Not really, just figured we might be able to head it off earlier

LGTM

Hi, do you plan to make a new release tag for this fix ? If so, when ?
