* 🔥 Remove hardcoded keepalive - fix homieiot#301 (homieiot#314)

Remove hardcoded KeepAlive for MQTT connection.
Default value of 15sec is already present in AsyncMQTT library

* 🐎 Improve uptime accuracy (homieiot#315)

improve uptime accuracy by storing milliseconds and only rounding when
publishing value
drawback: less time before rollover, but still long enough

* 🐛 Fix truncated IP (homieiot#318)

published IP is truncated.

* 🎨 Fix warning with parenthesis

* 🐛 Fix pio library.json bad dependency name

* ✨ Add support for static IP and BSSID/MAC, channel of AP (homieiot#327)

* Support for static IP and BSSID/MAC, Channel of AP

- added parameters to config.json which allow to define static ip, mask,
gateway, dns
- added parameters to config.json which allow to define BSSID and
channel of AP

To run device with defined static IP you have to define ip, mask and
gateway together.

To point device to connect to specific BSSID and channel you haveto
define bssid and channel together.

```

* 🐛 IHomieSetting::settings first, HomieNode-settings second! (homieiot#335)

*  IHomieSetting::settings first, HomieNode-settings second!

Set initialization priority of IHomieSetting::settings to value of highest allowed priority (101).

This allows other static variables to be of type HomieSetting<T>.

See https://github.com/euphi/HomieNodeCollection/blob/master/src/RGBWNode.cpp for example.

Note: As shown in the example it makes sense to have a static HomieSetting member, if you have a class that may be instantiated multiple times. (e.g. two LED Strips connected to the same ESP8266, as shown in https://github.com/euphi/ESP-LEDCtrl).
