Is your feature request related to a problem? Please describe.
This feature is not tied to a bug, but it would be very useful to be able to specify a function to convert an enum to a string within RadzenDataGridColumn(s), as enum names are not always suitable for user-facing interfaces, but the utilities for filtering by enum value within a radzen table are very convenient.

Describe the solution you'd like
A parameter that takes a method from TEnum -> string that converts all of the values of a given enum to a string using that conversion function when rendering the filter menu.

Describe alternatives you've considered
An alternative solution is obviously to treat the enum strings as text always, but this strips much of their functionality, and means the filter no longer allows you to select enum values from a checklist. A custom filter template can also be used to achieve a similar effect.

Additional context
I can't think of any additional context. If this feature is agreeable though, I'm more than willing to implement it and create a PR for it myself.

I'm not certain what you would want from the syntax, given DataGridColumn uses a string for Property and therefore there would not be type information available at compile time for a TEnum -> String function.
