+Package binarystr parses and renders string (and other) representations of binary data.

+as "bit encoding" or "bitstrings".
+
+For example, the original data:
+
+	[]byte("test")
+
+	// Or:
+	// []byte{0x74, 0x65, 0x73, 0x74}
+
+can be encoded to a bitstring via e.g. [BytesToStr]:
+
+	01110100011001010111001101110100
+
+And even formatted via [FmtBinStr]:
+
+	// For example, FmtBinStr("01110100011001010111001101110100", "", "", " "):
+	01110100 01100101 01110011 01110100

+	0111 0100
+	0110 0101
+	0111 0011
+	0111 0100
+
+Or can be converted to a series of "binary booleans" via e.g. [BytesToBool]:
