Added container type argument for love.data.hash

[EngineerSmith]

Changed love.data.hash to accept a container type as an argument. This will be a breaking change!

I made the issue #2015, and decided to implement it. If you believe this change is too breaking, or unnecessary, feel free to reject it.

This PR also updates the tests, and adds the change to the changes.txt

local ld = love.data
local data = ld.newByteData("helloworld")

-- old
local hashed = ld.hash("sha512", data)
-- above replaced by
local hashed = ld.hash("string", "sha512", data)

-- new functionality
local hashed = ld.hash("data", "sha512", data)

The 12.0-development branch has been merged into main now, you'll need to change the base branch of this PR to main as well.
