Native parser does not allow indentation mismatch at EOF

[isidentical]

Short reproducer: (Only happens when the LIBCST_PARSER_TYPE=native)

import ast
import libcst

src = "if bleh:\n  print()\n "
ast.parse(src) # works perfectly
libcst.parse_module(src) # INDENT of 2 space does not match with indent of 1 space

0,0-0,0:            ENCODING       'utf-8'        
1,0-1,2:            NAME           'if'           
1,3-1,7:            NAME           'bleh'         
1,7-1,8:            OP             ':'            
1,8-1,9:            NEWLINE        '\n'           
2,0-2,1:            INDENT         '\t'           
2,1-2,6:            NAME           'print'        
2,6-2,7:            OP             '('            
2,7-2,8:            OP             ')'            
2,8-2,9:            NEWLINE        '\n'           
3,0-3,0:            DEDENT         ''             
3,0-3,0:            ENDMARKER      ''

Another way to repro, including the error message:

❯ printf 'if bleh:\n  print()\n ' | cargo run
    Finished dev [unoptimized + debuginfo] target(s) in 0.05s
     Running `target/debug/parse`
Parse error for stdin: tokenizer error: no matching outer block for dedent

Seems like this is only a problem at the end of the file. Mixed indents are otherwise completely fine AFAICT.
