Release v0.5.4.0

Better late than never. Fixes #3.

As noted in #3, these were apparently released without ever making it
into a commit. Thankfully changes are pretty harmless.

Alec Theriault authored 6 years ago and Ryan Scott committed 6 years ago

Summary:
This matches exactly the 'Read (Array i e)' instance defined in base.
Note that the same thing is being done for 'Show (UArray i e)'.

Summary:
The old Travis script still had targets to test against GHC < 8.0,
and wasn't using Cabal `new-build` among other things.

The fact that this was previously hidden appears to be an oversight and
I've needed it at least once.

The recent overflow check made the code stop working w/ prior versions
of GHC. But there's little benefit in support much older GHCs, so it's
easier to just cut the support window.

The ghc-8.2 and master branches disagree on the order of the instances.
Normalise this difference away.

Previously it failed with,

-T229: Data.Array.Base.safe_scale: Overflow; scale: 4, n: 4611686018427387904
-CallStack (from HasCallStack):
-  error, called at libraries/array/Data/Array/Base.hs ...
+T229: Ix{Int}.index: Index (17) out of range ((0,-1))

No overflow check is necessary in the case of Bool arrays since the array size
is actually smaller than the number of elements it contains. Moreover, we can
use setByteArray# to initialize the array.

As akio points out, the fix to #229 which I authored previously was blatantly
wrong.

Fixes GHC #4505.

Changing InstEnv to UniqDFM changes the order some things get
printed
