Fix weekday variant ordering: EY should be variant 1, not IY

[ptarjan]

Duplicate of cmusphinx/cmudict#50 — submitted here per discussion in cmusphinx/cmudict#53 about which repo is canonical.

Summary

• Swap variant ordering for FRIDAY, MONDAY, SATURDAY, TUESDAY, and WEDNESDAY so the standard EY /eɪ/ pronunciation ("-day") is the main entry
• Fix THURSDAY'S which had IY as the main entry despite THURSDAY itself already having EY first
• Now all 7 days of the week consistently have EY as the main entry

Problem

Five of the seven days of the week had the reduced IY /iː/ pronunciation ("-dee") listed as the main entry, with the standard EY /eɪ/ ("-day") as variant (1). This was inconsistent — SUNDAY and THURSDAY already correctly had EY first.

Word	Before (main)	After (main)
FRIDAY	F R AY1 D IY0	F R AY1 D EY2
MONDAY	M AH1 N D IY0	M AH1 N D EY2
SATURDAY	S AE1 T ER0 D IY0	S AE1 T IH2 D EY2
TUESDAY	T UW1 Z D IY0	T UW1 Z D EY2
WEDNESDAY	W EH1 N Z D IY0	W EH1 N Z D EY2
SUNDAY	S AH1 N D EY2	(unchanged)
THURSDAY	TH ER1 Z D EY2	(unchanged)

Evidence

All major dictionaries list /eɪ/ as the primary pronunciation:

• Cambridge: /ˈwenz.deɪ/, /ˈmʌn.deɪ/, etc.
• Merriam-Webster: /ˈfrī-(ˌ)dā/, /ˈmən-(ˌ)dā/, etc.
