Updating alpaca-java to use crypto v1beta3

[jessethouin]

As the title implies, I have updated this project to use Alpaca's new v1beta3 API, which has quite a few changes (some of which I haven't tested yet). Should I simply create a pull request from my fork? You can view it here - https://github.com/jessethouin/alpaca-java/tree/crypto_v1beta3

Hey @jessethouin! I really appreciate your contributions. Yes, please create a PR and I can review it in the next week or so. I'd encourage rigorous testing before creating the PR though.

[jessethouin]

Done, and rigorous testing in my personal project. :)

@Petersoj @jessethouin I am seeing crypto endpoints returning a 404. I cloned the repo to make the changes, but I couldn't pin point where I need to make the url changes.

@jessethouin @Petersoj Nevermind, I was using the crypto endpoint incorrectly. You can ignore this.

Ok sounds good. I'm glad you were able to resolve you issue.

Hello, has anyone discovered any issues from the crypto upgrades? I am seeing 404s from several endpoints.
