Make show round-trippable for IdOffsetRange

[timholy]

This displays both the values and indexes of an IdOffsetRange:

julia> using OffsetArrays: IdOffsetRange

julia> IdOffsetRange(11:13, -2)
IdOffsetRange(values=9:11, indexes=-1:1)

It also adds a constructor so that this is round-trippable:

julia> IdOffsetRange(values=9:11, indexes=-1:1)
IdOffsetRange(values=9:11, indexes=-1:1)

Closes #179
Closes #193

I like this. Perhaps we should use 'indices' instead of 'indexes' to be consistent with the array summary convention?

[timholy]

There are some fixes that should probably go into 1.6.x, but once we start thinking about a 1.7 (or 2.0) release I would plan to merge this.

[timholy]

Have all bugfix PRs been merged? If so let's start on the next minor release.

[jishnub]

Yes the other PRs are for the 1.7 series

Looking forward to easier debugging already...
