Description
**Describe the bug**
Attempting to load a non-existent column from a Parquet file throws ArrayIndexOutOfBoundsException instead of a more specific error.
**Steps/Code to reproduce bug**
Try to load a single column name that does not exist from a Parquet file. For example:
```
Table.readParquet(ParquetOptions.builder().includeColumn("doesnotexist").build(), new java.io.File("data.parquet"))
```
throws the following exception:
```
java.lang.ArrayIndexOutOfBoundsException: 0
at ai.rapids.cudf.Table.(Table.java:96)
at ai.rapids.cudf.Table.readParquet(Table.java:974)
... 49 elided
```
**Expected behavior**
A more useful error exception/message should be used than an array index error.
