Implement SigmaDelta based on ESP-IDF API (espressif#6053)

Summary

This PR is refactoring of SigmaDelta HAL in order to use IDF instead of current Register manipulation approach.

Impact

Change in API:

uint32_t sigmaDeltaSetup(uint8_t channel, uint32_t freq);
changed to -->
uint32_t sigmaDeltaSetup(uint8_t pin, uint8_t channel, uint32_t freq);

void sigmaDeltaAttachPin(uint8_t pin); removed, no longer needed. Pin is attached in sigmaDeltaSetup()

Update package_esp32_index.template.json

Add ALPN support to WiFiClientSecure (espressif#5633)

This adds a function to WiFiClientSecure to set the ALPN protocol.

This is required for an MQTT client to connect to AWS IoT when using an AWS Custom Authorizer, as described here.

Example code snippet:

...
WiFiClientSecure wiFiClient;

// ALPN protocol, needed with AWS custom authorizer
const char *aws_protos[] = {"mqtt", NULL};

void setup() {
  wiFiClient.setCACert(AWSCAPEM);
  wiFiClient.setAlpnProtocols(aws_protos);
}
...

Added UM FeatherS2 Neo to boards.txt and added appropriate variants. (e…
