add releases and building info to README.md
Description
@adam-mercer @duncanmmacleod this adds two items to the main README:
- links to releases at the top
- "Building from Source" section, recommending conda for this task, as I assume you'd like people to use nowadays.
Please feel free to amend wording and add anything I may have forgotten.
Maybe Duncan could also add a sentence about the install scripts included in the conda directory, if these are intended to be part of the standard workflow? I haven't used them yet.
