file in the same way as any other line if it is short fields.

0702c63bc0 wasm: lots of doc additions and refactoring. Refactored the WASM memory heap usage to hopefully eventually account for a runtime-growable heap. Differentiate between supported TypedArray types for input SQL strings vs binding/fetching blobs. Might (untested) have implemented the ability to bind UtfNNArray values as blobs, where NN is one of 16 or 32.

766ba7917e wasm: corrected the propagation of text/blob values via UDFs. DB.exec()'s sql may now be an array of strings which get concatenated together before passing it on to sqlite3_prepare_v2(). DB.exec()'s callback now applies to the first statement which has result columns instead of only the first statement. Fixed a precedence but which caused isInt32() to report false positives.
