fix(data): add missing 3d and 1M Binance kline intervals (#312)

Binance supports 16 kline intervals (1s,1m,3m,5m,15m,30m,1h,2h,4h,6h,8h,
12h,1d,3d,1w,1M); the live-binance `Interval` enum listed only 14, missing
three-day (`3d`) and one-month (`1M`). Add both variants in Binance order
with their wire-format strings, and extend the exhaustive as_str test.
