correct temperature readings for defective ICs + misc. improvements

[ghost]

• correct temperature readings for defective ICs (issue reading temperature / workaround for defective ICs #5)
• add caveat/code sample in readme wrt. resetting the IC when setting new mode and/or sample rates
• rename _reset() to reset() ; move calibration stuff out of initialize() into reset()
• add wait_{temperature,pressure}_ready() functions and use them in initialize()
• add example code for setting up the sensor for a low power weather station (as per infineon's datasheet)

the changes above shouldn't break code using this library, maybe with the exception of wait_{temperature,pressure}_ready() which throw an exception when the mode isn't properly set in order to avoid infinite waits (but in that case such code would be broken/non-functional anyway).

hmm, the PR's automatic test fails at "Check formatting", no idea why. Would need some help here...

[ladyada]

@kattni can help you get it formatted

[FoamyGuy]

@taradiddles the CI system automatically checks the code with PyLint as well as Black code formatter. You can learn about them and how to use it on your Circuit Python code in the learn guide here: https://learn.adafruit.com/improve-your-code-with-pylint

[kattni]

@taradiddles As @FoamyGuy said, follow the instructions in the guide. Run black first. That's what's causing the Check formatting failure. Then the CI check will get to Pylint and we will deal with whatever comes next.

@FoamyGuy : I just saw your comment, no idea why I didn't receive an email notification (I did for @kattni 's ). Thanks for the link. It took me a bit of time to go through the errors since I'm a python noob but hopefully everything's fixed now.

[ladyada]

looks great, its ready for testing now
@siddacious or @kattni do you have a DPS310 to test with?

[siddacious]

@ladyada I've got one. I'll give it a whirl

[siddacious]

Looks great! Thanks for the help.

One small request and it's good to go.
Also @taradiddles feel free to add yourself to the authors 👍

[siddacious]

Please add a note to the docstrings for the wait_nnn_ready methods about which modes are supported so that hapless meteorologists aren't ambushed by wild Errors 🐅

[ghost]

@siddacious: ready... Had to learn a bit about docstrings and sphinx, hopefully everything's OK.

Also @taradiddles feel free to add yourself to the authors

Thank you ; maybe next time... (at least once I know python a bit better)
