Parsing of Temporal domains

[maayan25]

Describe the bug
When attempting to parse Temporal PDDL files using PDDLReader.parse_problem(), 2 different errors occur.

To Reproduce
Steps to reproduce the behavior (1):

1. Get office_robot domain and problem
2. Create a PDDLReader instance, and call its parse_problem() method.
3. See max recursion error.

Steps to reproduce the behavior (2):

1. Get IPC pathways domain and problem
2. Create a PDDLReader instance, and call its parse_problem() method.
3. See syntax error.

Expected behavior
A parsed temporal problem, as can be received when following the same steps as above, with the temporal IPC Sokoban domain and problem, which contains a "total-time" expression.

Screenshots
For office_robot domain:

File ".../python3.11/site-packages/unified_planning/io/pddl_reader.py", line 1089, in declare_type
    declare_type(father_name, type_declarations[father_name])
  [Previous line repeated 990 more times]
RecursionError: maximum recursion depth exceeded

For Pathways domain:

  File ".../python3.11/site-packages/unified_planning/io/pddl_reader.py", line 539, in _parse_exp
    raise SyntaxError(
SyntaxError: Found invalid expression: total-time. From line: 144, col 47 to line: 144, col 57

Software versions:

• OS: Ubuntu 24.04
• Python 3.11, pip 25.0
• Unified-Planning 1.2.0
• networkx 3.4.2
• pyparsing 3.2.1
• ConfigSpace 1.2.1

Hello @maayan25, the first error should be fixed in #665.

The second error instead is due to the fact that the unified-planning does not support the combination of the minimization of the makespan with other optimization objectives.
