Move CI to GitHub Actions

[giordano]

Close #26

[mileslucas]

oops too late

[mileslucas]

Suggested change

	on:
	push:
	branches: "master"
	tags: ["*"]
	pull_request:
	release:
	on:
	push:
	branches: ["master"]
	tags: ["*"]
	pull_request:
	branches: ["master"]

IIRC releases automatically create tags, so there's no need to have both in the CI.

Suggested change

	concurrency:
	# Skip intermediate builds: always.
	# Cancel intermediate builds: only if it is a pull request build.
	group: ${{ github.workflow }}-${{ github.ref }}
	cancel-in-progress: ${{ startsWith(github.ref, 'refs/pull/') }}

I've also been adding a job to CI for aqua tests to catch things like missing compat, etc. if you want to add it! Here's a copy from another JuliaAstro repo

Suggested change

	aqua:
	name: Aqua tests
	runs-on: ubuntu-latest
	steps:
	- uses: actions/checkout@v2
	- uses: julia-actions/setup-julia@v1
	with:
	version: '1'
	- uses: julia-actions/julia-buildpkg@v1
	- run: julia -e 'using Pkg; Pkg.add("Aqua")'
	- run: julia --project=@. -e 'using Aqua, UnitfulAstro; Aqua.test_all(UnitfulAstro, ambiguities=false)'

Mind doing a PR with the suggested changes? 😁

I'll do that tomorrow!
