Disable trim at the beginning and end of key

[MrDave1999]

There are methods such as DisableTrimStartKeys() and DisableTrimEndKeys() but it would be nice if there was a method to disable the trims both at the beginning and at the end of the keys.

For example:

new EnvLoader()
     .DisableTrimKeys()
     .Load();

new EnvParser()
     .DisableTrimKeys()
     .Parse(envFile);
