Unsupported Type: SparkConfigurations

[jreitz43]

Deployment throws error "ASWT0029: Unknown object type: SparkConfiguration" when deploying a notebook (example shown below) that has a reference to a custom spark configuration. I believe this may be a very similar issue to #11 where SparkConfiguration would need to be added to the allowed valid types in private/!SynapseObject.class.ps1 as well as private/Get-SynapseObjectByName.ps1 so that it can pretend that the object referenced is valid and exists.
Notebook:

{
	"name": "nb_example",
	"properties": {
		"folder": {
			"name": "utility"
		},
		"nbformat": 4,
		"nbformat_minor": 2,
		"bigDataPool": {
			"referenceName": "sparkSm",
			"type": "BigDataPoolReference"
		},
		"targetSparkConfiguration": {
			"referenceName": "CustomSparkConfig",
			"type": "SparkConfigurationReference"
		},

Failure:
