Work around wrong stream `Length`

[maxpmaxp]

Sample indirect objects:

141 0 obj
<</Subtype/Form/BBox[0 0 28.80002 11.99902]/Length 32/Type/XObject>>
stream

endstream
endobj
170 0 obj
<</Subtype/Form/BBox[0 0 84.39999 11.99902]/Length 32/Type/XObject>>
stream

endstream
endobj

Acrobat Reader displays an error message, but still shows the doc.

Desired behavior:

• When endstream token is not found exactly after Length bytes of stream data, go back to stream token and try to find the closest endstream token.
• If one found - log warning and continue parsing assuming stream content between stream and endstream
• If no endstream found - raise an error.
