**Additional context**
Jaycar, a popular Australia and New Zealand electronics store, sells environmental sensors which may have either BME085 or SPL06-007. While the BME085 is supported, the SPL06-007 is not, causing a few issues to those unfortunate enough to buy the unsupported version of the sensor.

(.e.g. of similar enquiries https://community.home-assistant.io/t/barometric-pressure-sensor-module-invalid-temperature/362518)

The request names no files, tests, or entry points. Start by reviewing how the existing BME085 support is organized and the linked community discussion, then determine the integration requirements for the Goertek SPL06-007; done means the sensor is supported rather than rejected or misidentified.
