Fix #272. Blob types should be accessible via byte[]

[schveiguy]

This should fix the regression in #272

ping @SingingBush let me know if this is suitable for your project, or if we need more types to be included.

I haven't tested this yet, so will wait for CI to see if I made any mistakes!

ping again @SingingBush, any comments? If I don't hear from you for a few days, I'll just merge this and close the issue.

Sorry been hectic recently. I'll try it out tonight and get back to you

I've looked through the PR and it seems reasonable but I've not run locally. I noticed that there are now tests for byte[] and ubyte[] so that seems fine.

I was also trying to get it to work with std.datetime.systime.SysTime as an alternative to std.datetime.date.DateTime. SysTime includes timezone which makes it useful if using the timestamp type in MySQL.

According to MySQL docs:

MySQL converts TIMESTAMP values from the current time zone to UTC for storage, and back from UTC to the current time zone for retrieval. (This does not occur for other types such as DATETIME.) By default, the current time zone for each connection is the server's time.

So being able to retrieve columns as SysTime would be handy

SysTime includes timezone which makes it useful if using the timestamp type in MySQL.

If this is a new feature, and not an already-existing feature, can you open a new issue on it? I want to focus and making sure existing code doesn't break for this release. I agree, returning a SysTime might be useful. We do have a custom mysql Timestamp type, but I admit I never used it.

If it does work in 3.1.0, can you give me an example?

@SingingBush let me know if there are other problems that need addressing. Will push a new release.
