feat: Allow specifying type for field in DB

[codekeyz]

@Table(converters: [SessionStatusConverter()])
class Session extends Entity<Session> {
  @primaryKey
  final int id;

  final SessionStatus status;

Currently, Yaroorm automatically stores SessionStatus as String COLUMN in the Database. We should be able to specify a Type eg: INTEGER, this will be more performant.

Something like this

class Session extends Entity<Session> {
  @primaryKey
  final int id;
  
  @TableColumn(type: int)
  final SessionStatus status;
