Cannot auto-read pointers to basic types

[nettrino]

Bug Report:

Failure to auto-read tx in case of a pointer to a basic type (failed to convert node to value, recovered converToValue: reflect.Value.Convert: value of type string cannot be converted to type *string)

Issue Description

I am currently auto-generating types form gqlgen and adding gogm directives on top of those. However, Optional values are emitted as pointers, which are nil in case the field is empty. As such, if a node has a field of type *string, this fails to deserialise, however succeeds if the field is declared as string.

Steps to Reproduce

Insert and lookup a node like the one below

type Test struct {
	gogm.BaseUUIDNode
	Name     *string      `json:"name,omitempty" gogm:"name=name"`
	Type     string    `json:"type" gogm:"name=type"`
}

Environment

	Value
Go Version	1.19.2
GoGM Version	2.3.6
Neo4J Version	4.4.0
Operating System	darwin/arm64

Would you be interested in tackling this issue

Yes

Likewise would like to support timestamps as follows:

	UpdatedAt *time.Time `json:"updatedAt,omitempty" gogm:"name=updatedAt"`
