Saved Parser Dependency with name

The daffodilBin() function is used to access a published saved parser as a dependency, for example:

```scala
libraryDependencies ++= Seq(
("org.example" % "dfdl-fmt" % "1.0.0").daffodilBin(daffodilVersion.value)
)
```

But if saved parser was created and publish with a `name`, e.g.

```scala
packageDaffodilBinInfos := Seq(
DaffodilBinInfo("/schema.dfdl.xsd", name = Some("messages"))
)
```

Then it is not possible to reference that saved parser using `daffodilBin()`.

To fix this, the `daffodilBin()` function should be changed to take a `name: Option[String]` parameter that defaults to None, and if provided is used to get the saved parser that matches the name field in DaffodilBinInfo.

Start by locating the daffodilBin() entry point and the DaffodilBinInfo handling referenced in the issue, then trace how saved parsers are selected. The work is done when daffodilBin() still supports the default case and can select a saved parser by an optional name matching DaffodilBinInfo.
