Use `carray`` extension to bind array of numerics and strings, so we can avoid large and slow IN clauses, and cache prepared statements having a variable number of parameters. The extension is statically loaded and available in every connection. Consumers are encouraged to use the explicit `bindArrayXXX` methods, as the generic `bindByIndex` and `bindByName` methods are too lenient, especially from Javascript. Note `carray`` only supports UTF8 encoded strings, the API will convert the encoding when UTF16 is passed in. These new variants are not exposed to Rust yet, as the existing comment suggests they were intended for primitive types. It could be done in the future, if necessary.
