What does this PR do?

The date formats in the CEF guide describe the time formats in terms of Java's SimpleTimeFormat class.
The zzz specifier covers a few additional formats than what are covered by MST in Go's time format.
Namely on the Go side it was missing support for offsets (e.g. +04, +0400, +04:00). This change additionally
adds support for the ISO8601 Z time zone value (this does not strictly match the CEF guide's format).

For reference these are the Java SimpleDateFormats in the CEF guide:

MMM dd HH:mm:ss.SSS zzz
MMM dd HH:mm:sss.SSS
MMM dd HH:mm:ss zzz
MMM dd HH:mm:ss
MMM dd yyyy HH:mm:ss.SSS zzz
MMM dd yyyy HH:mm:ss.SSS
MMM dd yyyy HH:mm:ss zzz
MMM dd yyyy HH:mm:ss

Why is it important?

It makes the decode_cef parser more closely match the CEF guide specification.
