Remove uni5C3A-HK 尺 and its derivatives

[NightFurySL2001]

In v1.004, 尺 in TW is unified with CN. However, in v2.000, the difference is introduced with the addition of HK variant.

v1.004:

v2.000:

Consulting official documentations will find that the Taiwan education reference does not mention any requirements for 尺, and in Hong Kong Reference Glyphs it is viewed as a design difference, not a required standard.

The current design is very imbalanced with a notable empty space at the right and visual dark spot (joints) on the left.

I think there is no need to create a separate set of glyphs for characters with the 尺 components for HK.

• Strictly speaking, this HK version of 尺 also matches Taiwan's MoE standard. Since SHS didn't use a separate set of glyphs for TW in the first place, I believe there's no need to do so for HK.
• As mentioned in the HK Reference Glyph document (P.8), shifting the "㇏" stroke a little bit is seen as a design difference, not a violation of the standard (it's not a standard, but you get me. Not sure how to call it accurately). The document uses 尺 and 家 as examples.

• SHS didn't create a separate glyph set for characters containing "家" for HK.

• For some glyphs like 咫, 沢, 蚇 and 駅 the differences are small at heavier weights.
• This HK version may look nice in script form, but the JP/CN version definitely look better for serif and sans-serif fonts.

Therefore I suggest to remove the HK-specific glyphs for characters with the 尺 components, and use the JP/CN version (where appropriate) instead.

Followings are the codepoints concerned:

Codepoint	Suggestion
U+4F2C 伬	Use CN
U+544E 呎	Use CN
U+54AB 咫	Use CN
U+5C3A 尺	Use CN
U+5EB9 庹	Use CN
U+6CA2 沢	Use JP (also for TW)
U+8687 蚇	Use JP
U+99C5 駅	Use JP (also for TW)

Removing this unnecessary difference will save 8 glyphs.
