JS wrapper to implement common used Proxy Item pattern

[Pattern explanation](https://community.openhab.org/t/design-pattern-proxy-item/15991)

# Usage examples

```js

let proxy = require('openhab-proxy-pattern');

/*

proxy.bind(proxy_item_name, hardware_item_name).update([callback]).forward([callback]);

*/

// one direction proxy

proxy.bind('Equipment_WF_OutTemperature', 'SmartMAC_D105_1_T2').update();

// bi-directional proxy

proxy.bind("GF_Toilet_MirrorLight", "Shelly_25R_3_1Output")

    .forward()

    .update();

// proxy with custom values

proxy.bind('Equipment_ElectricityInverterBattery_Voltage', 'PZEM_1_Voltage')

    .update(function(value) {

        if (typeof value == 'string') {

            const v = parseInt(value) / 100;

            return `${v} V`;

        } else {

            return undefined;

        }

    });

// wide-options proxy

const v = function(value) {

    if (typeof value == 'string') {

        const v = parseInt(value);

        return `${v} V`;

    } else return undefined;

};

['A', 'B', 'C'].forEach(function(phase) {

    proxy.bind(`Equipment_ElectricityHomeV${phase}`, `Shelly_EM3_2_${phase}Voltage`, 15)

      .update(v, 15); // 15 seconds gap between updates. For too-fast hardware

});

```
