Convert TimeUnit to symbols

[hangy]

Here is a checklist you should tick through before submitting a pull request:

• Implementation is clean
• Code adheres to the existing coding standards; e.g. no curlies for one-line blocks, no redundant empty lines between methods or code blocks, spaces rather than tabs, etc.
• No Code Analysis warnings
• There is proper unit test coverage
• If the code is copied from StackOverflow (or a blog or OSS) full disclosure is included. That includes required license files and/or file headers explaining where the code came from with proper attribution
• There are very few or no comments (because comments shouldn't be needed if you write clean code)
• Xml documentation is added/updated for the addition/change
• Your PR is (re)based on top of the latest commits from the dev branch (more info below)
• Link to the issue(s) you're fixing from your PR description. Use fixes #<the issue number>
• Readme is updated if you change an existing feature or add a new one
• Run either build.cmd or build.ps1 and ensure there are no test failures

OK, this probably needs some discussion. 😊

I want to use localized versions of TimeUnit to localize ByteRate.Humanize, which currently only returns English time units.

Humanizer/src/Humanizer/Bytes/ByteRate.cs

Lines 51 to 78 in d073790

	public string Humanize(string format, TimeUnit timeUnit = TimeUnit.Second)
	{
	TimeSpan displayInterval;
	string displayUnit;
	if (timeUnit == TimeUnit.Second)
	{
	displayInterval = TimeSpan.FromSeconds(1);
	displayUnit = "s";
	}
	else if (timeUnit == TimeUnit.Minute)
	{
	displayInterval = TimeSpan.FromMinutes(1);
	displayUnit = "min";
	}
	else if (timeUnit == TimeUnit.Hour)
	{
	displayInterval = TimeSpan.FromHours(1);
	displayUnit = "hour";
	}
	else
	{
	throw new NotSupportedException("timeUnit must be Second, Minute, or Hour");
	}
	return new ByteSize(Size.Bytes / Interval.TotalSeconds * displayInterval.TotalSeconds)
	.Humanize(format) + '/' + displayUnit;
	}

I assume that a general method to get a symbol from the TimeUnit could be useful, which is why I added the TimeUnitToSymbolExtensions.ToSymbol method. However, I'm not quite sure how/if it was okay to leak Humanizer.Localisation.TimeUnit to a broader namespace. I'm open for any suggestions. 😊

What does the a mean here? Not sure I've seen this before, is there an example you can point to?

I took it from Wikipedia, which listed both "a" (per annum?) and "y" (per year) as possible versions in English. Will fix as discussed. 👍🏻

Thanks for the review! 🙂
