Release pakakeh.go v0.56.0 (2024-08-04)

== New features

* cmd/emaildecode: CLI to decode email body to plain text

The emaildecode accept file as input. If the email header contains
content-transfer-encoding with value quoted-printable or base64, it will
decode the message body and print it to stdout as plain text.

== Bug fixes

* lib/memfs: another fix for refresh

In previous commit we use wrong condition when handling directory
"." as Root.

== Enhancements

* lib/email: allow message that end lines with LF only

Although, a message from network must end with CRLF, a message from
(another) client may have been sanitized and end with LF only.

* lib/email: decode the message body based on content-transfer-encoding

After the header and body has been parsed, if the header contains
Content-Transfer-Encoding, we decode the body into its local formats.
Currently supported encoding is "quoted-printable" and "base64".

== Others

* lib/email: export the Header fields

By exporting the fields, this allow the caller to filter or manage
the field manually.

* _doc: add partial note and summary for RFC 2183

The RFC 2183 is define Content-Disposition header field in the
internet message.

* lib/ini: mention that marshaling []byte does not supported

Due to "byte" is considered as "uint8" during reflection, we cannot
tell whether the value is slice of byte of slice of number with type
uint8.
