    .SYNOPSIS
    Get-WeatherDetails - Cmdlet to get the weather details for a specific town and country.

    .DESCRIPTION
    The Get-WeatherDetails Cmdlet can get the weather details for a specific town and country using the Weatherstack API.

    .PARAMETER      Town
    The name of the town for which you want to get the weather details.

    .PARAMETER      Country
    The country code of the country in which the town is located.

    Available on: All plans
    By default, the API will return all results in metric units. Aside from metric units, other common unit formats are supported as well. You can use the units parameter to switch between the different unit formats Metric, Scientific and Fahrenheit.

    m for Metric:
    Parameter	Units
    units = m	temperature: Celsius
    units = m	Wind Speed/Visibility: Kilometers/Hour
    units = m	Pressure: MB - Millibar
    units = m	Precip: MM - Millimeters
    units = m	Total Snow: CM - Centimeters

    s for Scientific:
    Parameter	Units
    units = s	temperature: Kelvin
    units = s	Wind Speed/Visibility: Kilometers/Hour
    units = s	Pressure: MB - Millibar
    units = s	Precip: MM - Millimeters
    units = s	Total Snow: CM - Centimeters

    f for Fahrenheit:
    Parameter	Units
    units = f	temperature: Fahrenheit
    units = f	Wind Speed/Visibility: Miles/Hour
    units = f	Pressure: MB - Millibar
    units = f	Precip: IN - Inches
    units = f	Total Snow: IN - Inches
    
    .PARAMETER      access_key
    Your API key for the Weatherstack API.

    .INPUTS
    [string]Town
    [string]Country
    [string]Unit
    [string]access_key

    .OUTPUTS
    A PSObject with the weather details for the specified town and country.

    .EXAMPLE
    Get-WeatherDetails -Town "London" -Country "GB" -Unit "m" -access_key "[Your API Key]"

    This command will get the weather details for London, GB in metric units.
