Add AlexW-578's mods

[Krzeszny]

Add AlexW-578 and their 3 mods

• The mod id matches the harmony id if used by the mod and starts with the same id as your author folder
• All used links are valid
• Your ResoniteMod.Version must match the version being added in the manifest and follow Semantic Versioning
• Your AssemblyVersion should match the mod version
• You have included an accurate sha256 hash for each artifact
• Do not remove old mods. Instead, use the deprecated flag
• Follow the Resonite Policies and Guidelines and Mod Submission Guidelines

Some minor inconsistency with 'co.uk.alexw-578' vs 'co.uk.AlexW-578'.
The folder for these and 'co.uk.alexw-578.CustomProtofluxBrowser' use lowercase, the other two mods use uppercasing.

[XDelta]

Their mods seem to mostly use co.uk.AlexW-578 so I'd say to update the folder to that casing.

[Krzeszny]

Alright, and I'll decapitalize the ID's because the source code has them without capitalization

[Krzeszny]

Nevermind, the Harmony ID's are capitalized in all mods but CustomProtofluxBrowser and the manifest matches them. Alright, I think we're done here.

Still learning GitHub, bear with me. Should I squash these 9 commits?

Just updated the CustomProtofluxBrowser mod to be consistant to my other mods.
All mods now use co.uk.AlexW-578.

Can make another release if this needs to be also reflected within the dll file.

@Krzeszny don't worry about extra commits, they are squashed when merged. @AlexW-578 if you want to do so now, it can be added onto this PR, otherwise probably okay for a future release.
