Add unison v04 keyboard (#11982)

* Update: JonesのMIDIキーマップをベースに初期作成。AudioとMIDIの同時使用はファームウェアサイズ的に厳しい。

* Update: Unison用のIDへ変更

* Update: Audioはデフォとせず、OLEDをデフォとした。

* Update: v03基板から実際に動くものとなったため、v01からv03に変更。基本的な設定を完了。

* Update: 基本的なキーマップを作成

* Update: キーマップ、ロータリーエンコーダの感度を調整。

* TEST: BOOTMAGIC = lite　でどうなるのかテスト

* Update: Jones ---> Unison

* TEST: BOOTMAGIC = lite で、TABキーでBootloaerに入る設定

* Update: インデント

* Update: QMKの一般的な表記に合わせ、 k(col)(row) から k(row)(col) へ変更。

* Update: 自前のカスタムマトリクスを使用せず、COL2ROW方式で総当たりマトリクスを動作させるテストを開始。

特に問題なく動作している。

* TEST: BOOTMAGICテスト用コード追加

* Update: 主に中央部分のキーマップ変更

* TEST: COL2ROWで、COLのピンの順番を変えてキーを読むテスト

* Update: QMKの仕様上、MacではKC_PSCRがFキーとして判定されるため、スクリーンショット用マクロを用意した。

* TEST: COL2ROWで、ROWとCOLのピン定義をずらした状態で、BOOTMAGIC = lite の（0,0)キーに引っかからない。

* Update: ロータリーエンコーダにマウスホイールを割り当て

* Update: 自明のコメントを削除

* Update: NKRO指定時は、NKRO動作を強制。

* Update: MIDIなしのとき、AUDIOのフル機能がファームウェアサイズ内に収まることをチェック。

* Update: Bootmagicテスト完了のため、無効化。

* TEST: LED動作チェック。

* Update: キーマップを、LOWER, RAISEを中心に大幅変更。

数字を左手レイヤーキーではなく、右手レイヤーキーにしたことで、CMD+Qによる誤爆アプリ終了を避ける狙いもある。

* Update: 未使用のNumレイヤとTapDanceを削除。

* Update: MIDI関連の設定を多数追加。

* New: Add Sequencer keymap

* enumの開始を明記

* TAP_DANCEを無効化

* シーケンサーで、トラック単位の有効・無効の切り替えを追加。※動作せず

* デバッグ用設定をテスト
