feat: Duration for sql representation + aggregation support

[chloeminkyung]

Aggregation Support

• Avg - AVG(DURATION) -> DURATION
• Count - COUNT(DURATION) -> INT
• Max - MAX(DURATION) -> DURATION
• Min - MIN(DURATION) -> DURATION
• Sum - SUM(DURATION) -> DURATION

SQL Representation

• INTERVAL '1' SECOND
• "6/04/2023 10:00" + INTERVAL '30' SECOND
• "6/04/2023 10:00" - INTERVAL '30' SECOND

Currently only supported TimeUnits are:

• SECOND with up to u64 due to https://web.mit.edu/rust-lang_v1.25/arch/amd64_ubuntu1404/share/doc/rust/html/std/time/struct.Duration.html#method.from_secs
• MILLISECOND or MILLISECONDS with up to u64 due to https://web.mit.edu/rust-lang_v1.25/arch/amd64_ubuntu1404/share/doc/rust/html/std/time/struct.Duration.html#method.from_millis
• MICROSECOND or MICROSECONDS with up to u64 due to https://web.mit.edu/rust-lang_v1.25/arch/amd64_ubuntu1404/share/doc/rust/html/std/time/struct.Duration.html#method.from_micros
• NANOSECOND or NANOSECONDS with up to u64 due to https://web.mit.edu/rust-lang_v1.25/arch/amd64_ubuntu1404/share/doc/rust/html/std/time/struct.Duration.html#method.from_nanos
