Add support for 0x5f36 devices and RM4 series (#317)

Browse Source 
* Add support for 0x5f36 devices

This type of device requires a header in the payload. The rest is the same.

* Improve request header assignment

* Change code sending header

I just found out that this device uses a different header for sending codes. This update addresses this issue.

* Improve authentication

Use the error code to check if the authentication was successful.

* Use default value when devtype is None

* Use generic remote type if devtype is None

* Extend support to RM4 series

I just realized that RM4 devices use the same header. I will take the opportunity to extend support to these devices as well.

* Add device type 0x62be and create rm4 class 

The rm4 class will improve code scalability. Just add the RM4 type to this class and it will just work.

* Remove comma
