Subject: [PATCH] Use platformio's extend feature (#149)

* Use platformio's extend feature

* Pin ESP32 platform version

* Do not use env: prefix for base envs

By using a custom prefix base:, we don't need to list the environments we *want* to build explicitly.

* Fix espressif32 platform version
