<#
    .SYNOPSIS
    Create a new column in Microsoft Dataverse.

    .DESCRIPTION
    Add a new attribute / column to a table using CreateAttributeRequest.
    Use typed constructors such as New-XrmStringColumn, New-XrmBooleanColumn,
    New-XrmIntegerColumn, New-XrmDecimalColumn, New-XrmDoubleColumn,
    New-XrmMoneyColumn, New-XrmDateColumn, New-XrmChoiceColumn,
    New-XrmMultiChoiceColumn, New-XrmFileColumn, New-XrmImageColumn,
    New-XrmMemoColumn, and New-XrmAutoNumberColumn to build the
    AttributeMetadata object.

    Relationship-based lookups require specialized SDK messages and should use
    Add-XrmOneToManyRelationship or Add-XrmPolymorphicLookup instead of
    Add-XrmColumn.

    .PARAMETER XrmClient
    Xrm connector initialized to target instance. Use latest one by default. (Dataverse ServiceClient)

    .PARAMETER EntityLogicalName
    Table / Entity logical name.

    .PARAMETER Attribute
    The AttributeMetadata object defining the column.

    .PARAMETER SolutionUniqueName
    Solution unique name to add the column to.

    .PARAMETER IsAuditEnabled
    Whether auditing is enabled on the column. When specified, overrides the value set on the AttributeMetadata.

    .OUTPUTS
    Microsoft.Xrm.Sdk.OrganizationResponse. The CreateAttribute response.

    .EXAMPLE
    $attr = [Microsoft.Xrm.Sdk.Metadata.StringAttributeMetadata]::new();
    $attr.LogicalName = "new_code";
    $attr.SchemaName = "new_Code";
    $attr.DisplayName = New-XrmLabel -Text "Code";
    $attr.MaxLength = 50;
    Add-XrmColumn -EntityLogicalName "account" -Attribute $attr;

    .EXAMPLE
    $attr = New-XrmBooleanColumn -LogicalName "new_enabled" -SchemaName "new_Enabled" -DisplayName "Enabled" -DefaultValue $true;
    Add-XrmColumn -EntityLogicalName "account" -Attribute $attr;
