CUBRID dialect support

**Blocked by:**
https://github.com/devastool/entity2jooq/issues/27

**Description:**
1) Need to create `CUBRIDTypeMapper` class, that extends from `DialectTypeMapper`, dialect name should be `CUBRID`;
Example:
```java
public class CUBRIDTypeMapper extends DialectTypeMapper {
public CUBRIDTypeMapper() {
super("Postgres", Set.of(...))
}
}
```
2) Need to add new dialect to `RouteTypeMapper` constructor.
Example:
```java
public RouteTypeMapper() {
CUBRIDTypeMapper cubridMapper = new CUBRIDTypeMapper();
dialects.put(cubridMapper.getDialect(), cubridMapper);
}
```
