### Description

I came across the following while trying to serialize SQL data to xavp (`sql_xquery()`) and then serializing the result to htable using `xavp_params_implode()`. One of the data columns has a type of `BIGINT`. The resulting string had neither the key nor value.

I recognize that Kamailio does not currently have support for 64 bit integers and that adding support for it is probably not a trivial matter. My request here is really that if the value is going to be dropped it would be good if `pv` would omit a warning.

#### Reproduction

MySQL table:

```sql CREATE TABLE dids ( id INT NOT NULL AUTO_INCREMENT PRIMARY KEY, did varchar(11) NOT NULL, route_id BIGINT NOT NULL, failure_route_id INT NOT NULL, description VARCHAR(255) ); ```

With data like this: ```sql INSERT INTO dids ( did, route_id, failure_route_id, description ) VALUES ( '15555551000', 101, 1006, 'Alice' ); ```

And the following Kamailio code: ``` $var(query) = "SELECT * " + "FROM dids " + "WHERE did = " + $(rU{sql.val.str});

sql_xquery("db", "$var(query)", "did_data"); xavp_params_implode("did_data", "$sht(did=>$rU)"); xinfo("Serialized query result: [$sht(did=>$rU)]\n"); ``` The following log line results - the `route_id` is missing all together: ``` 1(7) INFO: <script>: Serialized query result: [id=1;did=15555551000;failure_route_id=1006;description=Alice;] ```

### Possible Solutions

It's worth noting that the value is usable out of the XAVP. `$xavp(did=>route_id)` is retrievable, and the problem seems to be only when running `xavp_params_implode()`. In a perfect world, the key and value would be retained and put into the serialized data, however I'm not sure of the complexity of this (what if the the value exceeds a 32 bit int?, etc). With that said, my only real request would be that if a value is dropped that a warning is omitted with a rough explanation of the reason ("omitting _keyName_ unknown_ data type", etc).
