Added example 'get mac address' (espressif#8618)
* Example sketch prints MAC for different interfaces Interfaces described in documenation: https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/system/misc_system_api.html#mac-address * Update README.md to include 'MacAddress' * Add files via upload * Delete libraries/ESP32/examples/MacAddress/GetMacAddress.ino * Delete libraries/ESP32/examples/MacAddress/GetMacAddress/GetMacAddress.ino * Delete libraries/ESP32/examples/MacAddress/GetMacAddress/MacAddress directory * Add files via upload * Add files via upload * Adds necessary MAC header file * Reverting - moving to the sketch * Adds include with esp_mac_type_t values --------- Co-authored-by: Jan Procházka <90197375+P-R-O-C-H-Y@users.noreply.github.com> Co-authored-by: Rodrigo Garcia <rodrigo.garcia@espressif.com>

* GetMacAddress
3+
*
4+
* This sketch prints out the MAC addresses for different interfaces.
5+
*
6+
* Written by: Daniel Nebert

*
8+
* The first printed MAC address is obtained by calling 'esp_efuse_mac_get_default'
9+
* (https://docs.espressif.com/projects/esp-idf/en/release-v5.1/esp32/api-reference/system/misc_system_api.html#_CPPv425esp_efuse_mac_get_defaultP7uint8_t)
10+
* which returns base MAC address which is factory-programmed by Espressif in EFUSE.
11+
*
12+
* The remaining printed MAC addresses is obtained by calling 'esp_read_mac'
13+
* (https://docs.espressif.com/projects/esp-idf/en/release-v5.1/esp32/api-reference/system/misc_system_api.html#_CPPv412esp_read_macP7uint8_t14esp_mac_type_t)
14+
* and passing in the 'esp_mac_type_t' type.

esp_mac_type_t values:
19+
20+
ESP_MAC_WIFI_STA - MAC for WiFi Station (6 bytes)
21+
ESP_MAC_WIFI_SOFTAP - MAC for WiFi Soft-AP (6 bytes)
22+
ESP_MAC_BT - MAC for Bluetooth (6 bytes)
23+
ESP_MAC_ETH - MAC for Ethernet (6 bytes)
24+
ESP_MAC_IEEE802154 - if CONFIG_SOC_IEEE802154_SUPPORTED=y, MAC for IEEE802154 (8 bytes)
25+
ESP_MAC_BASE - Base MAC for that used for other MAC types (6 bytes)
26+
ESP_MAC_EFUSE_FACTORY - MAC_FACTORY eFuse which was burned by Espressif in production (6 bytes)
27+
ESP_MAC_EFUSE_CUSTOM - MAC_CUSTOM eFuse which was can be burned by customer (6 bytes)
28+
ESP_MAC_EFUSE_EXT - if CONFIG_SOC_IEEE802154_SUPPORTED=y, MAC_EXT eFuse which is used as an extender for IEEE802154 MAC (2 bytes)
