> 2\. Allow to specify the `occurence` keyword, given that this is not
necessarily obvious, it's nice to be able to specify the named argument:
Actually, that errors only because I mis-spelled the keyword name. With the
correct name it works:
```
>>> pc.map_lookup(arr, pa.scalar("a"), occurrence="all")
<pyarrow.lib.ListArray object at 0x7f099c96bd00>
[
[
"a1"
],
[
"a2"
],
[
"a1"
]
]
```
Wondering if we can provide a better error message in that case, but that
might just be a Python/cython behaviour of first checking the positional
keywords before the named ones)
