change(esp_now_serial): No teardown on retry limit (#10293)

Browse Source 
* change(ESP_NOW_Serial): No teardown on retry limit

After max retries is met once the ESP_NOW_Serial_Class performs "end()". 
This removes the peer from ESP_NOW. 
Further messages to and from ESP_NOW_Serial are not received or sent. 
Peer should stay in ESP_NOW to re-establish connection even with data loss. 
This change will "retry and drop" the data piece by piece instead of aborting the connection.

* feat(espnow): Add remove on fail parameter

* feat(espnow): By default keep the peer when sending fails
