Large batch of single character amendments

[jkwchui]

Over the past weeks I diligently went through the single character pronunciations for about 6,200 entries, and identified about 200 items that I believe is better served by an amendment. At the moment I have the items in a CSV file of the following format:

char	old	new
筒	tung2	tung4
簷	jim4	sim4
粘	nim4	zim1
累	leoi3	leoi6
縣	jyun4	jyun6
羡	jin4	sin6
翹	hiu3	kiu4

Given the scope, maintainers would probably need discussion of whether each entry is included or not. What is the best way of facilitating that process?

多謝你嘅貢獻。最好開一個 PR，然後我哋可以逐個檢查然後提意見。

Now that I start merging my changes into char.csv, it looks like the issue is not with rime-upstream but that PyCantonese takes the first match regardless of its tag (e.g., accepting 罕見 instead of 預設). I'll continue through the list but it looks like I should be raising the issue with them instead.
