1.项目后端整体迁移至PaddleOCR-NCNN算法，已通过基本的兼容性测试 2.工程改为使用CMake组织，后续为了更好地兼容第三方库，不再提供QMake工程 3.重整权利声明文件，重整代码工程，确保最小化侵权风险 Log: 切换后端至PaddleOCR-NCNN，切换工程为CMake Change-Id: I4d5d2c5d37505a4a24b389b1a4c5d12f17bfa38c

overview
[magic]
- magic number : 7767517
[layer count] [blob count]
- layer count : count of the layer line follows, should be exactly the count of all layer names
- blob count : count of all blobs, usually greater than or equals to the layer count
layer line
[layer type] [layer name] [input count] [output count] [input blobs] [output blobs] [layer specific params]
- layer type : type name, such as Convolution Softmax etc
- layer name : name of this layer, must be unique among all layer names
- input count : count of the blobs this layer needs as input
- output count : count of the blobs this layer produces as output
- input blobs : name list of all the input blob names, separated by space, must be unique among input blob names of all layers
- output blobs : name list of all the output blob names, separated by space, must be unique among output blob names of all layers
- layer specific params : key=value pair list, separated by space
layer param
0=1 1=2.5 -23303=2,2.0,3.0
key index should be unique in each layer line, pair can be omitted if the default value used
the meaning of existing param key index can be looked up at operation-param-weight-table
- integer or float key : index 0 ~ 19
- integer value : int
- float value : float
- integer array or float array key : -23300 minus index 0 ~ 19
- integer array value : [array size],int,int,...,int
- float array value : [array size],float,float,...,float

the model binary is the concatenation of all weight data, each weight buffer is aligned by 32bit
weight buffer
[flag] (optional)
[raw data]
[padding] (optional)
- flag : unsigned int, little-endian, indicating the weight storage type, 0 => float32, 0x01306B47 => float16, otherwise => quantized int8, may be omitted if the layer implementation forced the storage type explicitly
- raw data : raw weight data, little-endian, float32 data or float16 data or quantized table and indexes depending on the storage type flag
- padding : padding space for 32bit alignment, may be omitted if already aligned
