Singular Long Name Not Used for Single Values

[stiefeljackal]

In the current version (0.1.12 as of writing) of Elements.Quantity, the singular form of the long name of a unit is not used for single values. The following PowerShell demonstrates the bug:

# PowerShell

Add-Type -Path "Z:\Path\To\Elements.Quantity.dll" # Path to DLL varies
$dayUnit = [Elements.Quantity.Time]::Day
$time = New-Object Elements.Quantity.Time -ArgumentList @( $dayUnit.Ratio  )
[Elements.Quantity.QuantityHelper]::FormatAs[Elements.Quantity.Time]($time, $dayUnit, "0.#", $true)
 
# Expected: 1 day
# Actual: 1 days 

Since Resonite utilizes Elements.Quantity, the same bug occurs there as well:

It was also shown in Yellow-Dog-Man/Resonite-Issues#768 as well.

I have a PR that should address this issue; it will be posted shortly.
