This pr adds (config.js toggleable) showUV_Index to the hourly and
current weather modules, with right now only openmeteo configured to
supply the data. Other providers could have support too by adding
`uv_index` to current and hourly.
For example the current weather looks like

positioned after sunset in the top row.
The following "hacks" are included and could be fixed to make it
cleaner, but the functionality is wanted and it works without problem.
- To hide entries where the UV Index is 0 i added an if statement to the
`hourly.njk` which is not how precipitation is handled.
The following are minor things that might not need fixing:
- The forecast option does not have UV support. This might not be
relevant since UV changes throughout the day but i tried to implement a
"max_UV" to openmeteo.js, but am not confident enough in JS to
accomplish that.
- The UV Icon is wi-hot and manually added to the `.njk`'s. This could
be made changeable by a config but does not seem relevant since wi-hot
is not used by anything else as far as i can tell.

They weren't applied to wrong classnames, this PR fixes that and also
expands the weather util tests

Fixes#2953
This is an attempt to fix the issue with precipitation amount and
percentage mixup. I have created a separate
`precipitationPercentage`-variable where the probability of rain can be
stored.
The config options now has the old `showPrecipitationAmount` in addition
to a new setting: `showPrecipitationProbability` (shows the likelihood
of rain).

### Yr
I tested the Yr weather provider for a Norwegian city Bergen that has a
lot of rain. I have removed properties that are irrelevant for this demo
from the config-samples below.
Config:
```js
{
module: "weather",
config: {
weatherProvider: "yr",
type: "current",
showPrecipitationAmount: true,
showPrecipitationProbability: true
}
},
{
module: "weather",
config: {
weatherProvider: "yr",
type: "hourly",
showPrecipitationAmount: true,
showPrecipitationProbability: true
}
},
{
module: "weather",
config: {
weatherProvider: "yr",
type: "daily",
showPrecipitationAmount: true,
showPrecipitationProbability: true
}
}
```
Result:<br/>

Code updates to support a new weatherobject element called precipitationUnits. For the 'forecast' and 'hourly' UI, the weather module will use this new element if it is not null (i.e. a provider has pushed some value into this object element). If the element is null, then default 'units' processing will still occur. This allows a provider to have a customn unit of measure for precipitation - e.g. Env Canada will use mm for rain and cm for snow.
