Preview: Open an IDT file with a "*" character if the "*" is only between nucleotides (RNA presets or unsplit nucleotides)

[NadezhdaPeskun]

Steps to Reproduce

1. Switch to Macro
2. Open from Clipboard
3. Add IDT sequence
   /52MOErG/*/i2MOErG/*/3Phos/

4.Select IDT >> Open

5. Save >> Select IDT >> Try to Save structure to IDT format

Actual behavior
User cannot Save the next sequences to IDT - it's OK
User can Open the next IDT sequences - it's error;
/52MOErG/*/i2MOErG/*/3Phos/
OR
/5Phos/*/i2MOErG/*/3Phos/

Expected behavior
The user should be able to open an IDT file with a "*" character if the "*" is
only between nucleotides or nucleosides (RNA presets or unsplit nucleotides).

And Error message should appear while user try to Open the next examples:
/52MOErG/*/i2MOErG/*/3Phos/
OR
/5Phos/*/i2MOErG/*/3Phos/

Tasks:

• Macro: Introduce IDT alias for monomers and RNA presets in library and Ketcher model ketcher#4310
• Import of modified IDT monomers #1899
• Export of modified RNA to IDT notation (modified IDT monomers) #1900
• Import of standard IDT monomers #1588
• Export of RNA presets to IDT notation (standard IDT monomers) #1654
  Issue
• Preview: User can save IDT with 5' phosphate but cannot open this file again. #1974
