Library monomer correction

[AlexeyGirin]

Background
In 2.23-rc.1 we implemented that version of 4-Formylbenzamide:
Location in the library: CHEM
Name in the library: 4-Formylbenzamide
Abbreviation in the library: 4FB
Attachment points/leaving groups: R1=NH2, R2=O

Problem:
Current implementation of attachment points is 'hidden' hydrogen that is one valence. That is why we can't make R2=O because it is two-valence

Solution
Replace that monomer with another one:

Location in the library: CHEM
Name in the library: 4-Formylbenzamide
Abbreviation in the library: 4FB
Attachment points/leaving groups: R1=NH2, R2=CHO
4-Formylbenzamide (1).zip

Alternatives
Re-implement current implementation :-)

No test cases needed for that particular feature
