Type conversion

Review converting from JavaScript to SQL types.

---

When working in JavaScript, types must properly map to the protocol's requirements. Both SQLite and Tableland's constrained version of it have some types that don't perfectly align. Additionally, any object that implements a toSQL method can also be used.

JavaScript	Tableland	Notes
null	NULL
undefined	NULL
Number	INTEGER	Tableland supports 64-bit signed INTEGERs internally, and we mostly support BigInt on the client side. These values will be converted to INTEGERs. Note that Javascript integer's are safe up to MAX_SAFE_INTEGER $(2^{53} - 1)$.
String	TEXT
ArrayBuffer	BLOB
Booleans	INTEGER	Booleans will be turned into integers where 1 is true and 0 is false.
Date	INTEGER	Dates are converted to their UNIX timestamp representation.
Object or JSON	TEXT	A plain old JavaScript object (POGO) that can be converted to JSON strings will be converted to JSON and inserted as TEXT.
