AVRO-3495: Use the lookup table when comparing values against fields by name
Until now it was expected that both the schema fields and the input
values are sorted the same way.
Use BTreeMap instead of HashMap for the lookup table because otherwise
the assertion on the validation error messages is impossible due to
random printing of the map's entries

> Project: Apache Avro
> Issue Type: Bug
> Components: rust
> Reporter: Martin Tzvetanov Grigorov
> Assignee: Martin Tzvetanov Grigorov
> Priority: Major
>
> Initially reported at: [https://github.com/flavray/avro-rs/issues/47]
>
> Trying to validate and write a record from the following struct:
> {code:java}
> #[derive(Deserialize, Serialize)]
> pub struct MyRecord {
> b: String,
> a: i64,
> }
> {code}
>
> using this schema:
> {code:java}
> {
> "type": "record",
> "name": "my_record",
> "fields": [
> {"name": "a", "type": "long"},
> {"name": "b", "type": "string"},
> ]
> } {code}
>
> fails because the order of the fields is not the same.
