Error when using workspace-defined package metadata.

IE: https://doc.rust-lang.org/cargo/reference/workspaces.html#the-workspacepackage-table
Specifically:

error: proc macro panicked

    = help: message: Error parsing Cargo.toml: InvalidManifest("`version` in [package] section is not a string")
    = note: this error originates in the macro `fll` (in Nightly builds, run with -Z macro-backtrace for more info

[package]
name = "XXXX"
version.workspace = true
authors.workspace = true
edition.workspace = true
license.workspace = true

Changing version to version = "1.0.0" fixes it.

Thanks for letting me know!

Personal note, I guess workspace support should also pay attention to the changes made in #93

Although it's not a complete fix, the patch below fixes the issue with building with fluent.
