ESP32 io/analog module: adc_oneshot_unit_init_cfg_t structure not initialized

[Fan LIN]

This code does not properly init the structure (to all zero), leads to random initialization failure:

moddable/modules/io/analog/esp32/_analog.c

Line 256 in dd55984

 adc_oneshot_unit_init_cfg_t unit_cfg; 

Error message:

E (3505) esp_clk_tree: esp_clk_tree_src_get_freq_hz(21): unknown clk src
E (3509) adc_oneshot: adc_oneshot_new_unit(106): clock source not supported

needs to be:

adc_oneshot_unit_init_cfg_t unit_cfg = {};

Good catch. Thank you. I've applied your fix internally and it will propagate to this public repo in the near future.

This fix is now live. Thanks again.
