Dict parquet nested update

[ritchie46]

Continued from dict_parquet_nested. I thought I open a draft PR so we can make PR's on this branch more easily.

This fixed a few compilation problems and did a rebase on main. Remaining errors needs two missing function implemenations and a few other things where I don't really know what it should be:

error[E0425]: cannot find function `read_optional_values` in this scope
   --> src/io/parquet/read/deserialize/dictionary/nested.rs:121:17
    |
121 |                 read_optional_values(items, values, validity)

    |             ^^^^^^^^^^^^^^^ not found in this scope

error[E0599]: the method `by_ref` exists for mutable reference `&mut parquet::read::deserialize::dictionary::Optional<'_>`, but its trait bounds were not satisfied
   --> src/io/parquet/read/deserialize/dictionary/nested.rs:118:43
    |

    |                                           ^^^^^^ method cannot be called on `&mut parquet::read::deserialize::dictionary::Optional<'_>` due to unsatisfied trait bounds

            `parquet::read::deserialize::dictionary::Optional<'_>: Iterator`
            which is required by `&mut parquet::read::deserialize::dictionary::Optional<'_>: Iterator`
note: the following trait must be implemented

    | ^^^^^^^^^^^^^^^^^^
    = help: items from traits can only be used if the trait is implemented and in scope
    = note: the following trait defines an item `by_ref`, perhaps you need to implement it:
            candidate #1: `Iterator`
