IANA TZs should resolve in a case-insensitive way

[sandrock]

Hi. I found this promising project 15 minutes ago. I think a found a bug.

I think the library should resolve IANA time zones in a case insensitive way. The following unit tests show the problem.

[TestMethod]
public void TZDB_GetTimeZoneWithIanaId_EuropeParis_WrongCase_ShouldResolve()
{
    string input = "europe/paris";
    var result = TZDB.DB.GetTimeZoneWithIanaId(input);
    Assert.IsNotNull(result);
    Assert.AreEqual("Romance Standard Time", result.MicrosoftId);

    // FAILED
    // threw exception:
    // System.Collections.Generic.KeyNotFoundException:
    // The given key was not present in the dictionary.
}

[TestMethod]
public void TZDB_GetTimeZoneWithIanaId_EuropeParis_ShouldResolve()
{
    string input = "Europe/Paris";
    var result = TZDB.DB.GetTimeZoneWithIanaId(input);
    Assert.IsNotNull(result);
    Assert.AreEqual("Romance Standard Time", result.MicrosoftId);
    // PASS
}

Am I wrong?

hmm. this is a tricky one. If we are taking the lead of for example, java 8, the current behavior of being case sensitive is consistent with that implementation.
