TDIS perioddata written per period

[mjreno]

Version: Commit d50342f
Recreate:

• comment out OC constructor
• change time constructor:

time = ModelTime(perlen=[1.0, 1000.0], nstp=[1, 10], tsmult=[1.0, 1.5])
#time = ModelTime(perlen=[1.0], nstp=[1], tsmult=[1.0])

Result:

BEGIN OPTIONS
 START_DATE_TIME 1970-01-01T00:00:00
END OPTIONS

BEGIN DIMENSIONS
 NPER 2
END DIMENSIONS

BEGIN PERIODDATA 1
 1.0 1 1.0
END PERIODDATA 1

BEGIN PERIODDATA 2
 1000.0 10 1.5
END PERIODDATA 2

Note that current passing test also writes perioddata with a block variable of 1, but perioddata doesn't support block variables.

oops I think I broke the special casing that was supporting this up to now. I guess what we want is a generic way to support slicing blocks along a given dimension/coordinate as index.
