mir-algorithm v3.7.30: mir.date, squeeze, unsqueeze

[9il]

mir.date [1] is a rework of the Phobos Date type with the 
following features:

1. ABI and mangling compatibility with Boost's date type

2. BetterC compatible

3. ASDF (JSON) (de)serialization support

4. reworked all (to/from)String methods, added nothrow and @nogc 
versions

5. `toString` is the alias for `toISOExtString` instead of 
`toSimpleString`

6. Added universal `fromString` that parses ISO, Extended ISO, 
and Simple date strings.


`squeeze` and `unsqueeze` has been added to mir.ndslice.topology
