    <#
    .SYNOPSIS
        Retrieves a list of DHCP option spaces from BloxOneDDI

    .DESCRIPTION
        This function is used to query a list DHCP option spaces from BloxOneDDI.

    .PARAMETER Name
        The name of the DHCP option space to filter by

    .PARAMETER Protocol
        The IP version protocol to filter the DHCP option spaces by

    .PARAMETER Strict
        Use strict filter matching. By default, filters are searched using wildcards where possible. Using strict matching will only return results matching exactly what is entered in the applicable parameters.

    .PARAMETER Limit
        Use this parameter to limit the quantity of results. The default number of results is 100.

    .PARAMETER Offset
        Use this parameter to offset the results by the value entered for the purpose of pagination

    .PARAMETER Fields
        Specify a list of fields to return. The default is to return all fields.

    .PARAMETER OrderBy
        Optionally return the list ordered by a particular value. If sorting is allowed on non-flat hierarchical resources, the service should implement a qualified naming scheme such as dot-qualification to reference data down the hierarchy. Using 'asc' or 'desc' as a suffix will change the ordering, with ascending as default.

    .PARAMETER OrderByTag
        Optionally return the list ordered by a particular tag value. Using 'asc' or 'desc' as a suffix will change the ordering, with ascending as default.
