Subject: Drop ryml

Rapidyaml started refusing to parse config files so I dropped it.

* Add ConfigMarshal clas to support very simple config marshalling
  * No versioning, no type indicators, nothing.
  * Supports int, bool, and string.
  * Bool are serialized as int.
* Log no longer segfaults if given nullptr wxTextCtrl*.
* Fix how whisper CPP GUI fields restore from config

+RYML has decided to stop working and I don't want to spend any more time trying
+to figure out why.
+
+Let's make a parser that implements the small subset of YAML that
+Config.{h,cpp} rely on.
+
+Config needs to serialize the following types:
+
+* std::string
+* bool
+* int
+
+Bool will be serialized like ints, with additional requirements on
+deserialization.
+
+Serialization looks like this:
+```
+ConfigMarshall cm(out_);
+cm.Append("microphone", microphone_);  // string
+cm.Append("rows", rows_);              // int
+cm.Append("use_cpu", use_cpu_);        // bool
+cm.Write("config.yml");
+```
+
+Deserialization looks like this:
+```
+ConfigMarshall cm(out_);
+cm.Load("config.yml");
+cm.Get("microphone", microphone_);  // string
+cm.Get("rows", rows_);              // int
+cm.Get("use_cpu", use_cpu_);        // bool
+```
+
+Interface:
+```
+class ConfigMarshal {
+public:
+  ConfigMarshall(wxTextCtrl *out);
+
+  bool Save(const std::filesystem::path& path);
+  bool Load(const std::filesystem::path& path);
+
+  template <typename T>
+  bool Append(const std::string& key, const T& value);
+
+  template <typename T>
+  bool Get(const std::string& key, T& value);
+
+private:
+  std::map<std::string, std::string> kv_str_;
+  std::map<std::string, int> kv_int_;
+  std::map<std::string, bool> kv_bool_;
+}
+```
