Need to check & sort compilation flags
Introduces several helper crates, with the CLI moved to its own binary taking the `ironbar` name. The main bar now lives at `ironbard`, which the CLI will forward the `exec` to when appropriate. By moving the CLI into its own binary, it improves the startup time by over 30x, which means faster IPC communication. Resolves #1687 Related: #1488

Splits out the CLI into its own
ironbar-clicrate. The CLI uses theironbarbinary name, and the bar is moved toironbard.The CLI works as a proxy, and has exactly the same interface as the current binary. Executing just
ironbar(or any command without sub-commands) will forward to start the bar, whereas other requests stay within the CLI executable.By keeping IPC calls inside the CLI executable, it avoids the need to load the GTK libraries, which takes an approximate forever. This leads to an approximate 30x speedup in IPC commands, and a 7x reduction in memory needed.
A benchmark from the WIP version shows this:
The PR also introduces several other helper crates, mostly out of necessity to decouple the code in order to extract the CLI in the first place. These are:
ironbar-core- some central shared types.ironbar-args- the CLI argument types, as these are needed by both the CLI and main bar.ironbar-ipc-types- the command/response definitions for IPC, and base struct.The latter is exciting as it'll mean the IPC defintions will be published properly for the first time as a standalone crate, allowing rust-based integrations to be easily made.

Quite a bit of work to be done here still and some decisions to be made, but this works so publishing.
