v0.10.3 breaks FLOAT characteristic with minStep of 0.01

[ebaauw]

Analysis

See ebaauw/homebridge-rpi#143. I'm getting:

This plugin generated a warning from the characteristic 'Load': characteristic was supplied illegal value: number Infinity exceeded maximum of 1.7976931348623157e+308. See https://homebridge.io/w/JtMGR for more info.

When setting Load to a valid value, like 0.12, 0.2, or 0.07.

The characteristic is defined with type FLOAT and minStep 0.01. No maxValue nor minValue. I don't recognise Infinity, nor the maximum value mentioned in the warning.

After manually reverting to v0.10.2, the warning is gone.

Expected Behavior

Accept valid values, as v0.10.2.

Steps To Reproduce

Re-install Homebridge, so it installs hap-nodejs@0.10.3. Run Homebridge RPi.

The warnings are also gone after defining minValue and maxValue properties.
