Unescaped commas in CSV output

[chrisroman]

When running ./bloaty bloaty --csv, I get the following output:

sections,vmsize,filesize
__TEXT,__const,2151456,2151456
__TEXT,__text,1321560,1321560
__DATA,__bss,1050450,0
__DATA,__data,449104,449104
String Table,325048,325048
__DATA,__const,305856,305856
Symbol Table,248208,248208
__TEXT,__cstring,95128,95128
Export Info,43544,43544
__TEXT,__gcc_except_tab,19040,19040
__TEXT,__unwind_info,11968,11968
[10 Others],11880,9762
Lazy Binding Info,9568,9568
Weak Binding Info,4784,4784
[__TEXT],4734,4630
Binding Info,3824,3824
Function Start Addresses,3304,3304
__TEXT,__eh_frame,3304,3304
[__LINKEDIT],3008,0
Rebase Info,2264,2264
Indirect Symbol Table,2240,2240

However, if you look at the 2nd row __TEXT,__const,2151456,2151456, you'll see that the section name is __TEXT,__const which messes up the CSV formatting. I would expect it to be something like "__TEXT,__const",2151456,2151456.

This is also the case when adding the -d compileunits.

This is a silly error in the code. The code defines CSVEscape() but does not use it.
