+ update generated xslt file

Update GitHub Actions to use upload-artifact@v4

SVGHMI: fix build exception when static file directory is missing

Various unrelated code quality enhancements and fixes with no effect on execution.

MQTT: allow publish and subscribe from user python code.

python runtime: fix exception when transfering files with identical content.

SVGHMI: add static file serving feature.

Added two buttons to add and remove files.
Files are stored in project inside a directory named "static",
itself located in svghmi CTN instance files. Exemple :
exemples/svghmi_csv_json_img_table/svghmi_0@svghmi/static/
Files are transfered as "extra_files", but with a prefix
added to their name to avoid conflics.

Make Input widget actionable. Includes example from kraskrom@github.

Merge remote-tracking branch 'origin/python3' into python3

Update README.md

SVGHMI: fix inverted behavior of SuppressBrowserOutput.

Tests: matiec version bump

py_ext: CSV Writer output FB interface: ERROR and RESULT are valid when ACK is TRUE.

+ updated svghmi_csv_json_img_table accordingly

IDE: fix exception when changing or resizing comments in FBD

PLCOpen editor: fix exception when using file open dialog

Consequence of wxPython 3 to 4 API changes.

IDE: Fix wrong red wire coloring in FBD, this time for good.

py_ext: fix CSV update happening only once.

py_ext: rework logic CSV reader FB output refresh logic.

Saving with CSV write FB now triggers CSV read FBs to refresh outputs immediately.

py_ext: fix CSV Writer

fix POU logic :
- SAVE is a BOOL
- invocation of py_eval on rising edge of SAVE
- remove save python argument

fix python:
- use no encoding for file open (python2)
- re-use detected dialect if any
- use no "rt+" and truncate since no need to re-sniff dialect for output file
- return "OK" instead of "#SUCCESS", preventing POU logic to ACK result
- support creating new line if writing just after last line
- support appending data on short rows

fix example:
- use a HMI:Button to trigger CSV write instead of HMI:Input +1
- reload CSVs on on each new CSV opened in file browser
- add display of CSV write output

IDE: Fix wrong red wire coloring in FBD

C runtime: move generated erpc interface in separate "service" directory

IDE: Fix PLCOpenEditor (wxPython4 menus) and drop broken PDF doc support.

Extend HMI:JsonTable, create Edit CSV POU, create example, add some doc (#41)

eRPC: Version bump

python_runtime: fix ExtendedCall register/unregistering.

eRPC: Server closes connection on exception to prevent client to block until timeout when it happens.

Add ExtendedCall to PLCObject as a replacement of RemoteExec and reflect it in eRPC interface.

ExtendedCall is a generic remote procedure call that runtime code can register to and that IDE extensions can call.
For example a fieldbus extension can use ExtendedCall to browse the fieldbus devices connected to the runtime.

Removed dependency in requirements.txt.

Note: paho's lostConnection callback got already disabled in previous commit.
