AvroReadSupport.setRequestedProjection in 1.11.1+ not backwards compatible with MAPS

using AvroReadSupport.setRequestedProjection in 1.11.1 reading a 1.10.0 generated parquet file sets MAP fields to null (and vice versa 1.10.0 reader against a 1.11.1 generated file) 

- Not using a projected schema works, the map fields are converted correctly.
In my case. Parquet file is generated by hive 
```java

CREATE TABLE parquetmaptest (
a string,
b MAP
)
STORED AS PARQUET
tblproperties(
"parquet.compression"="SNAPPY"
);
insert into parquetmaptest select "a",map("k1","v1","k2","v2");
```

Using parquet-avro 1.11.1 (and appropriate dependencies) result in field "b" being null. 
```java

data:null
row:{"a": "a", "b": null}
```
Using parquet-avro 1.11.0 (and appropriate dependencies) result in field "b" being  the right map value.  
```java

data:{k1=v1, k2=v2}
row:{"a": "a", "b": {"k1": "v1", "k2": "v2"}}
```

Commencez par le PQMapTest.java joint et le chemin AvroReadSupport.setRequestedProjection, en comparant parquet-avro 1.11.1 à 1.10.0 sur le fichier MAP généré par Hive. Reproduisez d’abord l’échec de la lecture projetée ; c’est terminé lorsque les champs de map projetés restent renseignés avec des fichiers et des lecteurs utilisant l’une ou l’autre version.
