v0.1.0

Added

• Initial release. Extracts printable character sequences from binary files,
  reimplementing the Unix strings utility in pure Python with no runtime
  dependencies.
• Four encodings via -e: 7-bit ASCII (s, the default), 8-bit extended
  ASCII (S), and UTF-16 little- and big-endian (l and b).
• -n to set the minimum string length, -t to print byte offsets in
  decimal, octal or hexadecimal, -w to treat all whitespace as part of a
  string, and -f to print the filename before each match.
• Reads from stdin when given no file arguments or a - argument, and accepts
  multiple files in one invocation.
• Exits quietly when the output pipe closes early, so sillystrings big.bin | head behaves like coreutils rather than printing a BrokenPipeError.
