feat: added min and max value to algorithms

[JinIgarashi]

@vincentsarago

Based on the discussion here (https://github.com/developmentseed/titiler/discussions/760), I added min/max settings for algorithms parameters. I think these min/max values can be useful to create UI parts dynamically from titiler endpoint.

some parameters are straightforward to set min/max values, but some are not easy to set. Could you also check these min/max values are appropriate?

settings are shown as follow.

• Hillshade

  azimuth: int = Field(90, ge=0, lt=360)
  angle_altitude: float = Field(90.0, ge=-90.0, lt=90.0)
  buffer: int = Field(3, ge=0, lt=99)

• Contours

increment: int = Field(35, ge=0, lt=999)
thickness: int = Field(1, ge=0, lt=10)
minz: int = Field(-12000, ge=-99999, lt=99999)
maxz: int = Field(8000, ge=-99999, lt=99999)

• TerrainRGB

interval: float = Field(0.1, ge=0.0, lt=1.0)
baseval: float = Field(-10000.0, ge=-99999.0, lt=99999.0)

@vincentsarago I added title and description based on #786 for title and description, I copied text from comments in source code, but there might be better title and description for algorithms (especially for terrarium and terrainrgb)

new response of /algorithm endpoint is shown at the below.

@vincentsarago I just got notification email for CI. I have no idea why only 3.10 failed. Could you rerun this job for 3.10?

[vincentsarago]

@JinIgarashi it failed because of linting issue. do you have pre-commit installed?

[JinIgarashi]

@vincentsarago ah, I see. sorry I missed the info at CONTRIBUTING.md. I will install pre-commit. also, thank you for merging the PR
