Mutation Testing Elements - Add support for frameworks that export in MTE

[SecretSheppy]

Lots of frameworks support exporting in the MTE format. I am currently adding the mtelib package which will provide a reusable range of methods for any framework that supports it. alongside that I am working on adding support for Mull

[SecretSheppy]

Other frameworks that can be supported immediately when this PR is completed:

• stryker-net
• stryker-js
• stryker4s
• infection

I've been experimenting with generating descriptions for Mull as it does not provide them, it has turned out pretty well:

I have just added a more precise version of the generic message specifically for deletion mutations. Instead of

Replaced x with ``

it will now just display

Removed x

Mull seems to have significant issues with "broken" mutations (mutations where the end position occurs before the start position, most commonly at (0, 0)). I have added a system that extracts the broken mutations and dumps them in a fwname-broken.json file. This ensures that the broken mutations do not cause errors.

which exports mutants that look like this:

I've just noticed that the new statuses have been automatically added to the overview table (nice to be surprised like that sometimes 🤣 ) though it does now scroll horizontally when you have some longer file paths. I'm not a huge fan of this so it might be good to work out a solution for that.

I forgot to mention but 4eb6ae7 Closes #44 and #33

stryker-net is supported, but has lots of block removal operations that often leave the pages full of very large blocks of repeated code. might need to look at collapsing these at some point.

The Mull framework for Marv can now attempt to fix broken mutations:

Its not 100% accurate, but you can usually deduce what it is trying to say very easily. I think having these show is preferable to just dumping them all.

For the moment, this can be solved by just disabling the Block removal mutation operation, if that's possible.
