Add support for ESP32 (#17)

* Add support for ESP32

* core: Check length of body before allocating

Frames with no body may be worth parsing, but should avoid the allocation
of zero-length bodies. Instead, we'll check if the body exists in the
parsed data and if that length is zero, return early with success.

Fixes #16

* misc: Run GitHub build actions on pull requests

* Add support for ESP32
