MIT license

This fixes and updates all missing license headers.

I've also found a nice Github Action that checks matched filenames for specific license texts using this tool.

You can see a successful run here. I've had to ignore Pluto notebooks as they are quite particular about their syntax.

OpticSim.jl/.licenserc.json

Lines 1 to 11 in 360dc8c

	{
	"**/*.jl": [
	"# MIT license",
	"# Copyright (c) Microsoft Corporation. All rights reserved.",
	"# See LICENSE in the project root for full license information."
	],
	"ignore": [
	"samples/notebooks/",
	"samples\\notebooks\\"
	]
	}

And finally, 2 important bug fixes + new feature => patch number upgrade.
