Improve conversion function stability

[holomekc]

Hi,
First of all thx for the awesome work!

I would like to suggest a minor enhancement, so the issue I will mention was totally my mistake and is not an issue of the adapter.

After updating I received issues like this:

Without the information which device and service is affected it is kind of difficult to figure out what created the issue. Therefore, I checked the code and added a try/catch block. The code section I adjusted was:

ioBroker.yahka/main.js

Lines 1588 to 1597 in f380bb7

	toHomeKit(value) {
	let newValue = this.toHKFunction(value);
	this.adapter.log.debug(`script: converting value to homekit: ${value} to ${newValue}`);
	return newValue;
	}
	toIOBroker(value) {
	let newValue = this.toIOFunction(value);
	this.adapter.log.debug(`script: converting value to ioBroker: ${value} to ${newValue}`);
	return newValue;
	}

I did the following:

toHomeKit(value) {
        try {
          let newValue = this.toHKFunction(value);
          this.adapter.log.debug(`script: converting value to homekit: ${value} to ${newValue}`);
          return newValue;
        } catch(error) {
           this.adapter.log.error(`Could not convert values to HomeKit for : ${JSON.stringify(this.parameters)}`);
           throw error;
        }
    }

It would be great if there were more information except the function themselves. But I am not sure if this is possible. At least it helped me to figure out which services are creating the issue.
