SHT4X driver heater timeouts are wrong #99067
Description
Describe the bug
Too small wait time causes heater function(sht4x_fetch_with_heater) to try to read results before they are ready and function returns an error.
static const uint32_t heater_wait_ms[SHT4X_HEATER_DURATION_IDX_MAX] = {
1000, 100
};
Data sheet says:
min typical max
0.9 1 1.1

Did not check what all else we should wait, but at least the sensor I am currently wrestling with fails every time with 1000ms (for 1s heat time) and passes with 1100ms.
Regression
- This is a regression.
Steps to reproduce
I had SHT45 wired. Just call the function and observe it failing. But note that this might work just fine with one sensor and fails with another(if we believe datasheet).
Relevant log output
Impact
Functional Limitation – Some features not working as expected, but system usable.
Environment
NRF9160 + SHT45. Should be reproducible with any zephyr HW/SW. Might need a special SHT45 HW to reproduce.
