Fix EMA seed window to slide past leading NaN values

Revert the fixed-window approach from v0.2.3 — EMA now collects
`length` valid (non-NaN) values starting from the first valid bar.
This fixes chained EMAs on derived series (MACD signal, TRIX,
DEMA/TEMA, Elder Force) where leading NaN caused complete
initialization failure or wrong seed values.

Closes #81

Fix tsi() momentum seed and EMA SMA-seed window with NaN inputs

tsi: seed momentum[0] with NaN instead of 0 to match PineScript
(close - close[1] is na on bar 0).

ema: use fixed-width window of first `length` bars for SMA seed,
averaging only non-NaN values. Previously skipped NaN positions
entirely, shifting the seed index by one per NaN.

Closes #79
Closes #80

Fix ta.percentrank() and ta.rci() to match PineScript behavior

percentrank: compare against previous `length` values only (exclude
current value), use count/length*100 formula.

rci: use tie-corrected Spearman formula so duplicate values in the
window produce correct results.

Closes #77
Closes #78
