Open the supplied file path for reading or writing.
The file content can be accessed via the `file` property of
the `SDClass` object--this property is currently
a standard `SdFile` object from `sdfatlib`.
Defaults to read only.
If `write` is true, default action (when `append` is true) is to
append data to the end of the file.
If `append` is false then the file will be truncated first.
If the file does not exist and it is opened for writing the file
will be created.
An attempt to open a file for reading that does not exist is an
error.
