pip3 installation

The pip install mentioned here was having issues, so we recommend installing a prebuilt release:

Download Malmo
- Download the appropriate prebuilt malmo release here (example: Malmo-0.37.0-Windows-64bit_withBoost_Python3.7.zip).

- Unzip the download somewhere for use.
Install Java
- Install JDK 8 (not 15)
- Set your JDK_HOME environment by:
  - Searching windows for "Edit the system environment variables"
  - Select "Environment Variables..."
  - Click "New..." or "Edit..." to create or edit the JDK_HOME variable
  - Set it to where the JDK was installed (example: C:\Program Files\Java\jdk1.8.0_261)
Install Malmo dependencies
- Use PowerShell to install dependencies automatically (it was worked for some).
- If that doesn't work, install the dependencies manually, using instructions here.
  - For ffmpeg, go here: https://ffmpeg.org/download.html
Test your install
- Try launching "Malmo\minecraft\launchClient.bat" by double clicking or via powershell
- Navigate to "Malmo\Python_Examples" and try running "tutorial_1.py" while the malmo client is running.
  - If you see "ImportError: DLL load failed: The specified module could not be found." you may have the issue I had mentioned here.
    - Search "C:\Program Files" for a folder called "zlib.dll". I found several copies, but I used the one that was part of my visual studio install.
    - Copy that file into "Malmo\Python_Examples"
    - Rerun "Malmo\minecraft\launchClient.bat" and "tutorial_1.py".
