Declare supported UNION features

This patch was authored and released by @gwynne.

Leverages the new dialect flags from vapor/sql-kit#144 to enable full UNION queries according to SQLite's support.

The increased SQLKit version requirement makes this a semver-minor change.

Support storing json in text columns

This patch was authored and released by @tanner0101.

Adds support for storing JSON in TEXT columns (#87, fixes #54).

Support multiple in-memory databases

This patch was authored and released by @tanner0101.

Adds a new parameter identifier to SQLiteConfiguration.Storage.memory (#86, fixes #79).

This string uniquely identifies the in-memory database. Connections that use the same memory identifier share data.

let configuration = SQLiteConfiguration(storage: .memory(identifier: "foo"))

Using .memory without specifying an identifier will generate a random value. Only connections using that specific configuration will share data. This means multiple connection sources can now be initialized with separate configuration structs in the same process.

Dialect trigger + version fixes

This patch was authored and released by @tanner0101.

Adds SQL dialect trigger options plus updates to latest SQLiteNIO changes (#85).

SQLiteRow.decodeNil check value

This patch was authored and released by @tanner0101.

Adds a missing check to ensure the value is not .null when calling SQLiteRow.decodeNil (#82).

Release Candidate 1

Updates to Swift 5.2 and macOS 10.15. Adds additional CI testing.

Release candidates represent the final shift toward focusing on bug fixes and documentation. Breaking changes will only be accepted for critical issues. We expect a final release of this package shortly after Swift 5.2's release date.
