There seems to be no reason why esptool is python single-impl.
Being python single-impl causes issues for consumer of the
dev-embedded/esptool dependency. For example, dev-embedded/esp-idf (from
::guru), currently declares the dev-embedded/esptool dependency without
[${PYTHON_USEDEP}] as consequence of this.
