Feature description

Currently the public header only contains esp_err_t esp_hosted_slave_ota(const char* image_url); in https://github.com/espressif/esp-hosted-mcu/blob/main/host/api/include/esp_hosted_ota.h

It would be helpful to expose these functions https://github.com/espressif/esp-hosted-mcu/blob/main/host/drivers/rpc/wrap/rpc_wrap.h#L96-L98

If someone wants to write their own OTA where the coprocessor image will be sent via some custom protocol these functions are required.

And for rpc_ota_write the ota_data param should be const.

Use cases

Custom OTA protocol.
