描述

### Describe the bug, including details regarding any error messages, version, and platform.

The `Uint4Vector` set methods only accept an `int` type. I have some `uint32` values which I currently hold as `long` values in Java, as Java does not support unsigned integer types; long ensures no overflow. When writing to Arrow though, I would like to write it as its true `uint32` representation. Similar issue with `Uint8Vector`, where it only accepts `long` and no `BigInteger`. I did notice that `Uint2Vector` _does_ allow input as either `int` or `char`; so just seems the other UInt structures were neglected.

调研方向

先从 issue 中描述的 Uint4Vector 和 Uint8Vector 的 set 方法开始,然后将它们接受的输入与现有的 Uint2Vector int 和 char 重载进行比较。当 Uint4Vector 能够表示相关的 uint32 值,并且 Uint8Vector 能够在不发生溢出的情况下接受所需的 BigInteger 值时,工作就完成了。
