Changelog of @hackage/cabal-matrix 1.0.2.0

1.0.2.0

--blank-project is a new mode for building packages directly from hackage, and is a much faster alternative to --install-lib. It works by creating a temporary cabal.project file, whose contents are simply
```
extra-packages: target1, target2, ...
```
This causes target1... to be interpreted as simultaneously a package to be downloaded from hackage, and a package to be considered local, i.e. included in the "build" step and excluded from the "deps" step.
--constraints is a new option for specifying build constraints. It allows specifying one or more constraints on package versions with --constraints "foo >1 , bar <2". It also allows specifying implication constraints such as --constraints "foo >1 :- bar <2" e.g. as if all versions foo >1 were revised to include a bar <2 constraint. More generally it allows specifying disjunction constraints separated with ;, such as --constraints "foo >1 ; bar <2 ; baz ==3". Disjunction/implication constraints are translated to constraints guarded behind automatic cabal flags.

Binary operator options can now be parsed/formatted as JSON in a more compact way: foo --times bar --times baz can now be serialized/deserialized as {"times":[foo,bar,baz]}
--package PACKAGE (i.e. without any version or version range specified) now stands for all versions of PACKAGE. Likewise in JSON {"package":"PACKAGE","versions":null} now stands for all versions.
In the TUI, a build can now be:
- interrupted with Ctrl+C
- terminated with Ctrl+\
- prioritized with P
- restarted with R
