improve panic message for slice windows and chunks
before:
```text
thread 'main' panicked at 'size is zero', /rustc/1e225413a21fa69570bd3fefea9eb05e33f8b917/library/core/src/slice/mod.rs:809:44
```
```text
thread 'main' panicked at 'assertion failed: `(left != right)`
left: `0`,
right: `0`: chunks cannot have a size of zero', /rustc/1e225413a21fa69570bd3fefea9eb05e33f8b917/library/core/src/slice/mod.rs:843:9
```
after:
```text
thread 'main' panicked at 'chunk size must be non-zero', src/main.rs:4:22
```
