Add - UseSnakeProperCaseNamingConvention: FullName becomes Full_Name

[waywardcode]

Would be great to have UseSnakeProperCaseNamingConvention since the current UseSnakeCaseNamingConvention changes the column name to lowercase, where POCO's are then out of sync for those that manage larger projects and have some issues where 'People' are not distinguishing between lower and uppercase in class properties for documentation and generally using in SQL and POCO's -- so this is a feature request. :)

And a time saver when you have 1000's of these and probably will have 1000's more:

[Column("Employee_Id")]
public int EmployeeId { get; set; }

Thanks. I'm currently busy with other things, but later this year I plan a work cycle around this plugin - stay tuned.

Putting this in the backlog, but this should be pretty easy to implement if someone wants to submit a PR.
