v0.8.0-rc.1

Hi,

大家好，從 2022 年 4/29 開始的 Rust Rewrite (89ef2a8) 終於進入一個新的里程碑！
0.8.0 將會是第一個完全用 Rust 重寫的 libchewing 的第一個 release，希望大家幫忙
多多測試。

重大變更：新字典格式與舊有工具不相容

現有使用者字典將會自動備份及轉移，但舊有工具將無法直接操作字典檔案。
請使用新的 chewing-cli 工具來檢視、傾出或建構使用者字典。最終版本將提供更新的文件說明。

BREAKING CHANGE: New dictionary format is not compatible with old tools.
