Update to 1.11

Upstream changes:
1.11 [2024-06-25]
    The encoding of entities in xml() and save() has a new default:
        - only the <, >, &, and " characters are now encoded by \ 
default with HTML::Entities
        - key implication is that most multi-byte unicode characters are left \ 
as-is and no longer encoded as entities
        - users can revert to the previous default (which is equivalent to that \ 
of HTML::Entities) by explicitly setting unsafe_chars => undef

    Version argument in xml() is now implemented as key/value pair instead of a \ 
positional parameter

1.10 [2023-11-25]
    New methods for waypoints:
        - waypoint_rename(), waypoints_print(),
        - waypoints_clip() -- only supported on systems with the xclip utility

    New methods for tracks:
        - track_rename(), track_delete(), tracks_delete_all(), tracks_print()

    New method for routes:
        - routes_delete_all

    Fixed error when a filehandle is used as input
