Release 1.3.0!

[LilithHafner]

This is a big release. It also includes some technically breaking changes.

The biggest breaking change is adding comparative bench-marking which changes parsing syntax for cases where f is a comma separated list already.

For example,

@b rand(),rand()

Used to expand to

:((Chairmarks.benchmark)((()->(rand(), rand())); ))

and now expands to

:((Chairmarks.benchmark)(((()->rand()), (()->rand())); ))

which returns an NTuple{2, Benchmark} instead of a Benchmark.

Practically, I think this will not adversely impact folks and if it does, it would be perfectly fine to revert it in 1.3.1 and re-release as 2.0.0 because the whole comparative benchmarking scheme is experimental.
