parquet-format and parquet-format-structures defines Util with inconsitent methods provided

I have been running into a bug due to `parquet-format` and `parquet-format-structures` both defining the `org.apache.parquet.format.Util` class but doing so inconsistently.

Examples of this are several methods which include a `BlockCipher` parameter that are defined from `parquet-format-structures` but not `{}parquet-format{`}. While invoking code that happens to use these, such as `{}org.apache.parquet.hadoop.ParquetFileReader.readFooter{`}, the code will fail if the `parquet-format` happens to be loaded first on the classpath.

Here is an example stack trace for a Scala Spark application.
```java

Because of issues external to Parquet that I have yet to figure out (a complex Spark and dependency setup), my classpaths are not deterministically ordered and I am unable to pin the `parquet-format-structures` ahead hence why I'm chiming in about this.

Even if that weren't the case, this is a fairly prickly edge to run into as both modules define overlapping classes. `Util` is not the only class that appears to be defined by both, just what I have been focusing on due to this bug.
It appears these methods were introduced in at least 1.12:

Compare the org.apache.parquet.format.Util definitions in parquet-format and parquet-format-structures, focusing on the BlockCipher methods used by ParquetFileReader.readFooter. Reproduce the failure with parquet-format first on the classpath; done means the overlapping definitions are consistent and the NoSuchMethodError no longer occurs.
