    Gets a pricing unit with its corresponding distinct unit and block size.
 
    .PARAMETER UnitOfMeasure
    Optional. Unit of measure (aka pricing unit) value from a Cost Management cost/usage details or price sheet dataset. Accepts wildcards. Default = * (all).
 
    .PARAMETER DistinctUnits
    Optional. The distinct unit for the pricing unit without block pricing. Accepts wildcards. Default = * (all).
 
    .PARAMETER BlockSize
    Optional. The number of units for block pricing (e.g., 100 for "100 Hours"). Default = null (all).
 
    .DESCRIPTION
    The Get-FinOpsPricingUnit command returns a pricing unit (aka unit of measure) with the singular, distinct unit based on applicable block pricing rules, and the pricing block size.
 
    .EXAMPLE
