Bug in ds18b20_convert_and_read_temp

[lightoze]

&temp must be replaced with value here:

esp32-ds18b20/ds18b20.c

Line 483 in 0bb8f1b

err = ds18b20_read_temp(ds18b20_info, &temp);

@lightoze yes, you're absolutely right and I will fix it. I have only been using ds18b20_convert_all so didn't come across this obvious bug. Thank you for letting me know.

Should be OK now - thanks again.
