Alternative instances no longer require MonadPlus

[GregoryTravis]

Fixes #83 by requiring Alternative rather than MonadPlus in the Alternative instances for:

• Accum
• RWS/CPS
• RWS/Lazy
• RWS/Strict
• Select
• State/Lazy
• State/Strict
• Writer/CPS

Could I ask for this to be rebased and then we can re-review?

[GregoryTravis]

@L0neGamer ready for re-review.

[L0neGamer]

Looks like the CI caught some redundant constraints on some versions of ghc! Sorry for the slow feedback loop.

[GregoryTravis]

MHs seems to require a Traversible import that ghc 9.14.1 doesn't want. Trying an ifdef.

[L0neGamer]

Darn, yeah that's an issue we have. Sorry, would you be able to leave it in without the cpp? We can live with some warnings until #117 is merged when MHS updates.

[L0neGamer]

Just needs to undo the removal of imports in Lift and I think we're good to go!

[L0neGamer]

Again, sorry for the back and forth. further review which should be the last thing:

restore Writer.Lazy's imports
restore Except's imports
restore Identity's imports
restore Maybe's imports
restore Reverse's imports

[L0neGamer]

Writer Strict will also fail ;-; I must apologise again

Writer Strict will also fail ;-; I must apologise again

No problem -- what can I do to reproduce this locally so I can detect it myself?

[L0neGamer]

Installing mhs and mcabal and then do mcabal -r install in the directory

[L0neGamer]

Good to go!
