* Add initial support for multiple devices
Re-introduce support for multiple I2C devices (it was suppressed in df37a7635f). Devices are identified by their I2C address, and the BME680 can only have the 0x76 or 0x77 address, so this adds support for a maximum of two devices.

* Adhere to codebase standards
Obey the "All uses of class members and member functions should be prefixed with this-> to distinguish them from global functions in code review" rule of the Codebase Standards
* Fix formatting according to clang-format
* Perform the BSEC library reinitialization+snapshot only when more than one device is present
* Fix formatting according to clang-format
* Degrade abort message in restore_state_() from warning to verbose
This always happen at initial setup, so it's not a really useful message; when some real problems arise, we'll have a more useful warning from snapshot_state_()

* Reduce peak stack usage to avoid bootloops on ESP8266
Achieved mainly by moving the work_buffer needed by the BSEC library to the heap, as a single global work buffer shared by all instances.
::set_config_ has been reverted to a code path similar to the original, as that reduces peak stack usage enough to be OK on ESP8266 even without moving the work_buffer to the heap.

* Add support for devices with the same i2c address
Devices are now identified using their index in the BME680BSECComponent::instances member, which became a vector. This allows adding two devices with the same i2c address (which should be placed on different i2c buses). Since a BME680 can only have an address of 0x76 or 0x77, a maximum of 2 devices could be added before this commit. Now there is no theoretical limit on the number of devices which could be added.
