Add BlueIris profile monitoring and Fix Bytes format

[JulesL2]

Hi, I have developped a feature to monitor the active profile of BlueIris. It can be used in grafana with this example of visualization.

Moreover, I have updated the way the code handle the bytes units because blueiris logs have changed with the newest version old version: [300/432 hrs, 3.63T/3.63T, 5.33G free]

New version: [240/336 hrs, 459.4/460.0GB, 6.17GB free]

As there is no more the unit in the used storage and as there is also the GB vs G, I have extracted units and passed it as an argument to the function ConvertBytes. It works with a log that has got both formats.

Hope these pieces of code can be included in the code :)

Hi @JulesL2 thank you for the contribution!

I'm getting an error when I try and run your code. Looks like an issue with the updated regex. I'll take a closer look when I get a minute.

@JulesL2 Okay, I've suggested a few changes (most are nit picky formatting changes, sorry about that).
