[BUG]: Spell checking features for C

[zbreit]

Issue Description

Code Book does not currently spell-check the following C-language features:

// Macro functions and parameters
#define MACRO_FUNCTION(macro_param) macro_param + 1

// Named unions
union MyUnion {};

// Array declarations and fields
int nums[20];
struct { int ages[20]; };

// String content (other than function calls and initializers)
char* string;
string = "start\nthis should be spell-checked" "and so should this";

Steps to Reproduce

1. Create a C language file.
2. Copy the following snippet:

#define MACRO_FUNCTIONN(macro_paramm) macro_paramm + 1

union MyUnionn {};

int numss[20];
struct MyStruct { int agess[20]; };

char* str = "startt\nthiss shouldd bee spell-checked" "and so should thiss";

void foo() {
   str = "helooo";
}

Expected Behavior

Get spell check warnings for the following words:

• FUNCTIONN
• paramm
• Unionn
• numss
• agess
• startt
• thiss
• shouldd
• thiss
• helooo

Actual Behavior

No warnings appear.

Code Sample

See snippet above.

Log Output

Additional Context

Eventually, these fixes will also need to be ported to C++, but I can open a separate issue for that.
