About OffsetHexMode

[lishaoxia1985]

In the redblobgames.com, it seems that Pointy hex used EvenRows and OddRows, in the other way Flat hex used EvenColumns and OddColumns.
That means we only need to define an Enum like this:

OffsetHexMode {
Odd,
Even,
}

Hi @lishaoxia1985 , thanks for the issue. Good catch, I'll think about a good solution to avoid the confusion, either integrate the orientation in the conversion or have explicit docs

@lishaoxia1985 could you review #189 ?

[lishaoxia1985]

1. Do you think Rows and Columns is necessary?
2. Even and Odd can be as the parameter of fn to_offset_coordinate(), in fact we only use odd grid or even gird at the same time.

Yeah It might not make sense, just changed it in the PR

And we should add the necessary comment to describe.
