Cannot install 10.3.0 in Homebridge 1.6.0.

### What issue do you have? Please be as thorough and explicit as possible.

Installation of ewelink plugin claims to complete (green popup says installation successful), but the plugin does not appear in the plugin UI.   The module appears as expected in /var/lib/homebridge/node_modules.   The install can be repeated multiuple times with the same message.   By adding the login information to the platform section of the config file I can coax it into life, but I do not have access to (for example) set the ewelink plugin to run as a child bridge, and performace of other plugins seems to drop away.

### Details of your setup.
* Do you use Homebridge (with config-ui?) or HOOBS? 

Homebridge, config-ui.  Platform is Debian 11, latest packages, x86.  node is /opt/homebridge/bin/node v18.12.1.

* Which version of Homebridge/HOOBS do you have?

1.6.0

* Which version of this plugin (homebridge-ewelink) do you have? Has the issue started since upgrading from a previous version?

10.3.0.  I have also tried 10.2.0 and the beta, but the problem is the same.  I also have installed http-humidity, http-temperature, levoit-air-purifier, remote-air-quality-http, ring and tapo, all at the latest versions.  I have not had the same problem with those.

* Which eWeLink devices do you have that are causing issues? Please include product models if applicable.
