UUID parser silently ignores too long strings about poco

[bas524]

Hi, @omerbrandis. Your string contains 38 symbols include 4*-, but correct uuid should contain only 36 include 4*-

Hello @bas524,

this is the documentation for "tryParse" as taken from the header file:
/// Tries to interpret the given string as an UUID.
/// If the UUID is syntactically valid, assigns the
/// members and returns true. Otherwise leaves the
/// object unchanged and returns false.

my expectation is either :

1. if the input to tryParse is invalid for whatever reason, including if the string is too long and/or contains invalid characters, tryPasre will return false, as described in the documentation, but does not occur.
2. the documentation be amended to reflect the behavior.
