--lazy-quotes does not work for fields starting with quotes but not ending with

$ echo -ne "a,\"Cellvibrio\" Winogradsky 1929,c\n" 
a,"Cellvibrio" Winogradsky 1929,c

$ echo -ne "a,\"Cellvibrio\" Winogradsky 1929,c\n" | csvtk pretty -l
a   Cellvibrio" Winogradsky 1929,c 
-   -------------------------------

# `csvtk fix` did not fix this.
$ echo -ne "a,\"Cellvibrio\" Winogradsky 1929,c\n" | csvtk fix -l | csvtk pretty -l
[INFO] the maximum number of columns in all 1 rows: 2
a   Cellvibrio" Winogradsky 1929,c

However, when the quotes are only in the middle of fields, theres' no problem.

$ echo -ne "a,Cellvibrio\" Winogradsky 1929,c\n"
a,Cellvibrio" Winogradsky 1929,c
$ echo -ne "a,Cellvibrio\" Winogradsky 1929,c\n" | csvtk pretty -l
a   Cellvibrio" Winogradsky 1929   c

Added two commands:

• fix-quotes: fix malformed CSV/TSV caused by double-quotes.
• del-quotes: remove extra double-quotes added by `fix-quotes

Try it:

• csvtk_darwin_amd64.tar.gz
• csvtk_darwin_arm64.tar.gz
• csvtk_linux_amd64.tar.gz
• csvtk_windows_amd64.exe.tar.gz

$ echo -ne "a,\"Cellvibrio\" Winogradsky 1929,c\n" 
a,"Cellvibrio" Winogradsky 1929,c

$ echo -ne "a,\"Cellvibrio\" Winogradsky 1929,c\n"  | csvtk fix-quotes | csvtk cut -f 1-
a,"""Cellvibrio"" Winogradsky 1929",c

$ echo -ne "a,\"Cellvibrio\" Winogradsky 1929,c\n"  | csvtk fix-quotes | csvtk pretty 
a   "Cellvibrio" Winogradsky 1929   c
-   -----------------------------   -

$ echo -ne "a,\"Cellvibrio\" Winogradsky 1929,c\n"  | csvtk fix-quotes | csvtk del-quotes 
a,"Cellvibrio" Winogradsky 1929,c
